If A is the mother of B and B is the father of C, how is A related to C?

Answer and explanation

Correct answer: C. Grandmother

  1. Step 1: A is the mother of B, and B is the father of C.
  2. Step 2: The mother of one's father is one's paternal grandmother.
  3. Step 3: Therefore, A is the grandmother of C.
Answer
Grandmother.
Why not the others: Mother is one generation too low (A is the mother of C's father); Aunt assumes A is the sister of C's father; Sister confuses generational levels entirely.
