It is logical to infer that Mrs. Sommers avoided "such morbid retrospection" because a) she wanted to stay focused on her daily activities.  

Explanation:  

In the short story ‘The Silk Stockings’ by Kate Chopin, Mrs. Sommers was a one-time rich lady born into a poor family where she had to do all her household chores and look after her children.

Though she had seen better days as per her neighbors, but then she didn’t go into any morbid retrospection as she didn’t want to think of her past days as that wouldn’t help her at all in her present life. She wanted to work hard and spend money on her family and that too economically. So option a is the right answer.
