Options

A. `R xx Tdiv K`
B. `M + R xxT div K
C. `M - R xx T div K`
D. None of these

Answer

D

Explanation

R is grandson of K = R is the brother of the son daughter (M) of T whose father is K.
So, the required expression =
R + M x T`div`K or R + M `div` T `div` K.
OR R is grandson of K = R is the brother of the son daughter (M) of T whose mother is K.
So, the required expression =
R + M x T `xx` K or R + M `div` T `xx` K.
Therefore, none of the expressions represents the required relationship.
