Your first step on local rule questions should always be to draw the new rule, and make deductions. If O is in V, then K can’t be assigned to Y (the third rule).
A is wrong because one of K or N needs to be in (first rule).
B is wrong because if J is in, K needs to be in too (second rule).
C is wrong because K can’t be assigned to Y in this case (third rule) and L can never be assigned to Y (fourth rule). Y needs someone to be assigned to it.
D is wrong because K and N can’t go together (first rule).
E is CORRECT. L can be assigned to Z and N can be assigned to Y.
