Explanation
To find the expression where N is the daughter of K, we need to satisfy two conditions:
-
Gender: N must be female.
-
Relation: K must be one generation above N.
Let's evaluate the options:
Option (a): L # M # N"data−index−in−node="12">K \ \ L # M # N
-
L⟹K"data−index−in−node="0">K \ \ L⟹K is father of L.
-
L # M⟹L is brother of M.
-
M # N⟹M is brother of N.
-
Result: K is the father of N, but the gender of N is unknown (can be son or daughter).
Option (b): N ϵ L"data−index−in−node="12">M \ \psi \ K \ \ N ϵ L
-
N⟹K"data−index−in−node="0">K \ \ N⟹K is father of N.
-
N ϵ L⟹N is sister of L.
-
Analysis: Since N is a sister, her gender is confirmed as female. Since K is her father, N is definitely the daughter of K.
-
Result: This fits the requirement perfectly.
Option (c): K ψ M # L ϵ N
Option (d): N # M"data−index−in−node="12">L \ \psi \ K \ \ N # M
-
N⟹K"data−index−in−node="0">K \ \ N⟹K is father of N.
-
N # M⟹N is brother of M.
-
Result: N is a male (brother), so N is the son of K, not the daughter.
Final Answer:
In option (b), N is confirmed as female (sister of L) and K is her father.
Correct Option: (b) N ϵ L"data−index−in−node="20">M \ \psi \ K \ \ N ϵ L
