D. Examine her own perception and then check in with Ivan about his behavior
The question asks about what Tamara should to do better interpret the situation and communicate appropriately. In order for her to better interpret the situation she needs to examine her own perception. Why does she feel that Ivan is unusually quiet? Does she truly think that it is directed towards her? Then she should check in with him. Telling him that he's being inconsiderate as option A suggests is not helpful. Option B also does not solve the problem either. And if Ivan is going through something, offering him help or support may be what he needs. Option C is also not correct because Tamara should not be providing therapy and she doesn't even know what is going on.
The correct answer for the question that is being presented above is this one: "b. Mary had heard herself mentioned to Miss Bingley as the most accomplished girl in the neighbourhood; and Catherine and Lydia had been fortunate enough never to be without partners, which was all that they had yet learnt to care for at a ball"
The answer to your question is the third, fifth, and eighth sentence.
