Correct answer: Son-in-law
H>R: H is R's daughter. R$S: R is S's father, so S is R's son (S and H are siblings — H is female, S is male). S@T: S is T's son, meaning T is S's parent. T>N: T is N's daughter, so N is T's parent. T is female (daughter of N) and S is T's son — so S is the son of T, who is N's daughter. S is N's grandson? Wait: T is N's daughter, S is T's son — S is N's grandson. But answer should be son-in-law. Re-examining: S@T means S is the son of T (T is S's mother/father). T>N means T is the daughter of N. So T is female, N is T's parent. S is T's son. S is N's grandson. Hmm. But the given answer option is Son-in-law. Let me re-read symbols: 'K@D' means K is the son of D. So S@T = S is the son of T. T>N = T is the daughter of N. S is son of T; T is daughter of N. S is N's grandson. That contradicts Son-in-law. Unless H>R$S@T>N is parsed as H>(R$S)@(T>N) differently. Parsing left to right: H>R (H daughter of R), R$S (R father of S, so S is child of R, making H and S siblings where H is female), S@T (S son of T — but S is already R's son, so T=R? or this is a separate family?). If T=R then T>N means R is daughter of N. So N is R's parent; R is S's father; S is N's grandchild. Still grandson. The official SSC answer for this type of question is Son-in-law. Let me try: maybe '@' means something else. Re-read: 'K@D' = K is the son of D. So S@T = S is son of T. T>N = T is daughter of N. H>R = H is daughter of R. R$S = R is father of S. So chain: R is father of S AND H is daughter of R (H is R's daughter, hence H and S are siblings where H is female). S is son of T (T is a parent of S), and T is daughter of N. If H (female, sibling of S) is the wife of someone and S married T... wait, 'K<D' = K is wife of D. There is no '<' in the expression. Actually if we re-examine: maybe H is wife of R. H>R could be... no, H>R explicitly means H is daughter of R. Let me try: official answer for these coded-blood-relation Qs from SSC. Given the options, Son-in-law seems correct if T is S's wife. But S@T means S is son of T, not husband. Unless the answer in original paper is Grandson. Given ambiguity, I'll go with Grandson as my best answer.
