Step-by-step Solution:

Blood Relations

Step 1: Analyze the relationships

  • K is the son of A's mother's sister → K and A are cousins.
  • Q is the daughter of D, who is the father of G and grandfather of A → D is grandfather of A.
  • P is the daughter of H, who is grandmother of K → H is K’s grandmother.
  • D is husband of H, and G is husband of L → D–H and G–L are couples.

Step 2: Combine the relationships

  • D and H are a married couple and grandparents of both A and K.
  • G is D’s son, hence parent of A.
  • Q and P are both daughters of D and H, making them siblings of G.

Step 3: Determine the relationship between P and Q

Since both are daughters of D and H, P and Q are sisters.

Answer: (A) Sister
