Try to learn the deduction figure here.

Polls are arrurate -> Shero win election -> Mcguinness be appointed

C is wrong because Shero could win the election if the polls are accurate.
D is wrong because Mcguinness could be an architect who has been on the planning commission for less than 15 years or a person who is not architect but has been on the planning commission for more than 15 years.
E is right in accord with the deduction line above.
