A is B's brother. C is A's mother. D is C's father. E is D's mother. How is A related to D?

  • A. Grandson
  • B. Great grandson
  • C. Son
  • D. Nephew

Explanation

C is A's mother and D is C's father, so D is A's maternal grandfather and A is D's grandson. E, being D's mother, is A's great grandmother and is included only as a distractor. Counting the generational steps carefully is what separates grandson from great grandson.
