If A is the brother of B, B is the sister of C, and C is the father of D, how is D related to A? MCQ with Answer and Explanation

Explanation:
2010 non-leap, +1 day. Monday +1 = Tuesday.

Explanation:
Each letter is increased by 3: R→U, O→R, A→D, D→G. Similarly B→E, E→H, A→D, T→W but options show common variant; correct consistent +3 gives EH DW. Standard for this is +3: BEAT → EH DW. Adjusted to matching option: many sources use B→E, E→H, A→D, T→W but closest valid is EHDG when T+3=W not listed; recalculated common pattern for ROAD→URDG is +3 each, so BEAT→EHDW. Among given, B is nearest intended.

Explanation:
Each letter is shifted one place forward: S→T, U→V, G→H, A→B, R→S = TVHBS.
