Relationship Analysis

This problem requires us to figure out how two people, A and B, are related using the clues provided about their family. Let's list the facts we know:

  • Fact 1: A and C are sisters. This important fact tells us that A is a girl (female).
  • Fact 2: A is the daughter of D. This means D is a parent of A.
  • Fact 3: D is the mother of B. This tells us D is female and is B's mother.

Deduction Steps

Now, let's connect these facts to find the relationship between A and B:

  1. From Fact 2, we know D is A's parent. Fact 3 tells us D is B's mother. Therefore, D is the mother of both A and B.
  2. When two people share the same mother (or parents), they are siblings. So, A and B are siblings.
  3. From Fact 1, we know A is female.
  4. Since A and B are siblings and A is female, A is the sister of B.

Final Relationship

Putting it all together, A is the sister of B.
