Our behavior and interaction is a reflection of our convictions and accepted principles, and they determine us based on our actions towards others, which again depends on what we want and what not, what we strive for and what our ambitions and goals are.
C) It is ironic that the young married women have so much, and yet feel quiet unhappy.
Irony is when the opposite of what is expected happens. The entire passage describes how easy life is for the young married women in Floral Heights and other prosperous areas of Zenith. One would expect the women to be happy that they want for nothing and only have to work for two hours a day. They can spend their days in leisure, enjoying the company of their friends. However, at the end it is revealed that they are actually unhappy. This is the opposite of what is expected and therefore, ironic.
That is false. Hope I helped you :)
