A
If T, S and X are the only persons serving on committee B, Z and Y are the remaining members who have a complete membership of committee C. By the process of elimination B, C, D and E are inappropriate. What remains is A and rightly so. Take a look at the graph.
B
X and U can constitute the membership of committee C. Again by the process of elimination, B is the most appropriate answer.
Answers for 7  9
Let us use a graph to make answering the following questions easier:

D
M is the grandchild of O. Therefore choice A is not appropriate. It is possible that P is a female. Therefore, choice B is also not appropriate. Choice C is incorrect, as P for example may be a male and certainly could not have mated with N. Choice E is also incorrect because, if C is the grand daughter of O, she can be the daughter of P who may not have mated with N. Thus, C and M may be cousins, not sisters. Choice D is correct because if B is the daughter of N, M and B are sisters. Since M is also the daughter of N.
A
Choices B and C are not appropriate as these choices are not inconsistent with the premises. Choice D is a true statement. Choice E is not correct as N is the father of M, another party C could, indeed, be the mother of M. Choice A is correct: since N is the father of M, or cannot also be the father of M.
D
If B is the son of N, then B is a brother to M. If B has one brother D, then M is the sister of D. The statement I is correct. D and N cannot be brothers because N is the father of D. Thus statement II is not correct. O is the father of N, so O is the grandfather of D. Thus statement III is correct. Hence the choice is D.
