The correct answer is
Sister's son

Expression Breakdown

  • C - E: C is the brother of E. (This indicates C is male).
  • E ÷ G: E is the daughter of G. (This indicates E is female, and G is her parent).
  • G + I: G is the husband of I. (This establishes G as male and I as female, making G the father and I the mother of E).
  • Since C is the brother of E, C is also the son of G and I.
  • I x J: I is the sister of J. (This means J is a sibling of I).

Determining C's Relation to J

Based on the decoded relationships:

  • C is the son of I.
  • I is the sister of J.
  • Consequently, J is the brother of C's mother (I), making J the maternal uncle of C.
  • The question asks how C is related to J. Since C is the son of J's sister (I), C is J's nephew.
  • Option 1 correctly identifies this relationship as "Sister's son", referring to C being the son of J's sister.
