Answer 1

The Correct Option is C

To answer this question, we need to understand the conditions required for R to be the brother-in-law of K. For R to be the brother-in-law of K, two things must be true: - K must be married to R's sister or K's sibling (since "brother-in-law" implies that R is the brother of K's spouse). - R must be male. Based on the given symbols in the previous questions: - \( 1 \) means "K is the husband of R's sister" (so, K and R's sibling are married). - \( 3 \) means "R is the brother of K's spouse" (so, R is K's brother-in-law). Therefore, for R to be the brother-in-law of K, the statements that must be true are statements 1 and 3. Final Answer: \[ \boxed{1 \, \text{AND} \, 3} \]
