In The Necklace, what do the following lines mainly reveal about Madame Loisel?
The girl was one of those pretty and charming young creatures who sometimes are
born, as if by a slip of fate, into a family of clerks. She had no dowry, no
expectations, no way of being known, understood, loved, married by any rich and
distinguished man; so she let herself be married to a little clerk of the Ministry of
Public Instruction.
She dressed plainly because she could not dress well, but she was unhappy as if she
had really fallen from a higher station; since with women there is neither caste nor
rank, for beauty, grace and charm take the place of family and birth. Natural
ingenuity, instinct for what is elegant, a supple mind are their sole hierarchy, and
often make of women of the people the equals of the very greatest ladies.
a) She was the most beautiful girl in the entire country.
b) She felt entitled to riches because of her looks.
Oc) She came from a wealthy family.
Od) She wanted a career that offers a high salary.

Madame Loisel, as can be inferred from the paragraph, is not born in a wealthy family, but certainly possesses great beauty and charm. The statement, "She dressed plainly because she could not dress well, but she was unhappy as if she had really fallen from a higher station;" indicates her dissatisfaction with her humble situation, the sorrow of which she feels as though it were a step-down from a "higher-station."

Here, "higher-station" cannot be a major change in her financial situation after marriage, because she was born in a family of clerks and subsequently married a clerk. It, however, suggests that she felt that she was entitled to more than what she got, and that her not being able to dress well, or have luxury in a way, was like a step-down from what she deserved because of how she looked.
