Options

A. `C Delta M beta ^(**) E `
B. `P Delta C beta M beta E`
C. `O beta C beta N ^(**) M beta E`
D. None of these

Answer

D

Explanation

If C and E are to be cousins the generation gap between C and E must be zero But the gap is `1 + 0 + 1 =2` in choice `1, 0 + 0 + 0 =0` in choice `2, 0 + 1 + 0 =1` in choice `3, 0 + 1 + 0 =1` in choice `2, 0 + 1 + 0 = 1 ` in choice `3, 0 + 1 + 0 =1` in choice 4. So, choice 1, 3 and 4 are definitely wrong. Even 2 is wrong as `C beta M beta ` means that C is brother of E and not cousion.
