Answer:
She cannot imagine a way for a woman to survive on her own.
Step-by-step explanation:
Pygmalion is the play written by George Bernard Shaw. The play is a rendition of Greek myth.
In the play, Mrs. Higgins is a lady living in a Victorian Era. During the Victorian Era, there were many rules of dos and don'ts for each class. The upper-class women of the society were offered only a few career options as compared to today. Upper-class society women had one career option, that is marriage.
So, for Mrs. Higgins in the play, it was a matter of concern when Higgins and Pickering were performing a little experiment on Eliza, a flower girl. Mrs. Higgins said that though Eliza may learn the manners and etiquettes of duchess she can no longer go back on becoming a flower girl. She needs to have someone (through marriage) to look after her financially. She disapproved of woman earning to survive on her own.
"The manners and habits that disqualify a fine lady from earning her own living without giving her a fine lady's income!..." (Reference from Pygmalion).
So, the correct answer is the third option.
