Blood Relation Puzzle: A to C

This section breaks down the family relationships provided to determine how A is related to C.

Analyzing Key Connections

We are given the following crucial relationships:

  • A is the brother of B: This tells us A and B share the same parent(s), and A is male.
  • B is the son of C: This identifies C as the parent of B.

Deriving A's Relationship

Combining these points leads directly to the answer:

  • Since B's parent is C, and A is B's brother, C is also A's parent.
  • Given that A is male ('brother'), A must be the son of C.

The details about M, Q, and D are extraneous for this specific question.
