Analyze the expression F - G x H / I - J / K
F - G (F is wife of G), G x H (G is brother of H), H / I (H is son of I), I - J (I is wife of J), J / K (J is son of K).
Establish the Family Hierarchy
F and G are a couple (G is husband, F is wife). H is the son of I. Since G is brother of H, G is also a son of I. Since I is the wife of J, I is the mother and J is the father of G. J is the son of K.
Identify Relationship of G to K
G is the son of J. J is the son of K. Therefore, G is the son of the son of K, which makes G the grandson (Son's Son) of K.
B: Mother's brother is an uncle, which does not fit the generational gap; C: Father's brother is an uncle; D: Mother's father is a grandfather, but the lineage established shows G is the grandson, not the grandfather.
A is correct because the step-by-step genealogical derivation identifies G as the grandson (son's son) of K through the chain: G is son of J and J is son of K.
In blood relation coding, always check the gender of the person first; if the question asks for 'How is X related to Y', X's gender must match the option's gender category.
