The correct answer is A.
During the play Ruth is shown as a very unhappy and pessimistic character. Besides being the typical housewife, she also has to work in white houses as a maid. She lives with her husband and his family in a small, cramped house and is very dissatisfied with her situation.
Still, she stays and works because she is worried for her family and their economic situation. She even considers aborting against her own will to not put more financial pressure on her family members.
