Why does Myrtle act increasingly like a queen when she arrives in New York and then the apartment?

A. She wants Nick to know she's in charge

B. She believes her affair with Tom confers status upon her

C. She's the only woman Tom has ever cared about

D. She's raising Tom's child for him and believes they'll start a family

E. She's deluding herself that her husband is rich and regal

I would say the correct answer is B. She believes her affair with Tom confers status upon her.

Myrtle is having an affair with a married man, Tom. She is also married, to a poor owner of a car-shop. Therefore, when she started cheating on her husband with Tom, who is wealthy and respectable, she started having a better opinion of herself, thinking that she has become a lady now that she is in a relationship with a 'gentleman.'
