Caution: You are entering a boring adventure zone



You need to follow Reena's morning routine and answer the question:



How many doors did Reena physically open? (Total number of times she opened doors)




It was Sunday and Reena decided to do some chores. She cleared the
sink by putting the dishes in the dishwasher. She also cleaned the
microwave and the oven with a napkin. She took out a mug from a
cabinet and a tea bag from another and made herself a cup of tea in
the microwave. She liked her Tea with milk (which she got from the
fridge). She threw the old tea bag in the trash can in a cabinet under
the sink. Then she decided to do her laundry. The laundry room was on
the ground floor of her Apartment Complex (not on the first floor
where her place was). So she prepared for that time. Got her dirty
laundry from her closet, remembered to pick up some seat covers from
her balcony.



She was walking toward the elevator when she realized that it was
going to be a very hot day. So she turned back, went inside her
apartment and got herself an Ice Cream bar.



She then took the elevator to the ground floor and went to the Laundry
room. She used her card key to get in. She liked the fact that all the
machines were new and front loading type. She started the washer.
Twenty to thirty minutes. She decided to go to the Courtyard in the
middle of the complex. Had to use her card key again to enter the
courtyard.



The courtyard had a pool, vending, restrooms and lots of chairs. She
sat and ate her ice cream. Then she went to the courtyard rest room (nature calls).



There was a small locked room at the courtyard where they had books,
games etc. She went in. Searched a book cabinet and got a paperback to
read.



After a few minutes she went to the laundry room again. Washer was
done so she transferred the clothes to the dryer and started it.
Thirty more minutes!



Back to the courtyard and the book reading. Now she was a little
thirsty so she walked to the vending machines and got herself a big
bottle of soda.



In a few minutes she went to the laundry room to check on the dryer.
Clothes were not completely dry so needed to put another 10 minutes on
it. She had run out of quarters so she took the elevator and went in
her apartment. She kept lot of change in her fireproof safety box in
the closet. She took the quarters and this time took the stairs. Each
floor was door protected (card key again!).



Into the laundry room. She started the dryer again and waited there
till it was done. She folded the laundry and took the elevator back to
her apartment. Put the laundry inside the closet and rest of the
change in the safety box. DONE. Not really. She had brought the book
with her.



So she rushed back to the stairs and the courtyard bookroom and replaced
the book in the book cabinet. She came back to her apartment via stairs. Now DONE.




How many doors did she open?



Please chose from




A: Less than 60



B: 61



C: 62



D: 63



E: 66




Note



Only the following doors are spring loaded to close automatically



Apartment, balcony, laundry room, courtyard, restroom, stairs and bookroom



Assume the starting position of all doors to be closed.

          UPDATE: I think it is




          B, with 61 doors. This is also assuming that doors she opens she doesn't close.




          But I might be overlooking something! I have highlighted the added rows. Following is a picture of my table (I have a tough time getting images to work with spoilers, so just click the link):
