The author also describes the personality of Lady Middleton as being superficial and how she uses her son to start an irrelevant talk.
the first answer is C and the second is D
I am going to go with C (simple sentence) on this one because after the and you do not have another complete sentence therefore it would not be considered a complex sentence. Hopefully this helps.
