Although, for now, I've no idea of diagonal placement of a thing. But for d fact that options A, B and C are wrong, I'd rather choose option D. Both are neither metals, belonging to same period nor the same group.

Since they both have the tendency of losing electrons during reactions,i think they should both be METALS

The explanation is satisfying just that similar question was answered and A (as metals) was chosen to be the viable option.
Thanks.
