I believe your answer is D, because vertical angles are congruent
All the components in the state vector need to sum to 1. You're given that component corresponding to state 1 is 0.2, and that the component for state 3 is 0.
That leaves states 2 and 4, for which you're told that the component for state 2 is four times as large. If

is the component for state

, then you have

which means

. So the state vector is

.
Prime Factorization of 900= 2, 2, 3, 3, 5, 5
Prime Factorization of 212= 2, 2, 53
