Incorrect Inference:
Explanation:
- The given equation T # L $ M $ P 1 J Δ N n K implies the following relationships:
- T is the wife of L
- L is the father of M
- M is the father of P
- P is the son of J
- J is the mother of N
- N is the husband of K
- Based on the above relationships, we can infer the following:
- There are four males (L, M, P, N) and three females (T, J, K) in the family.
- L, M, and N are males.
- P and K are males.
- However, the inference that K is male is incorrect. This is because N is the husband of K, which means K is female.
Therefore, the correct answer is option C: K is male.
