Answer

A, B, C, D

Explanation

(A) `CH_(3)-CH_(2)-CH_(2)-CH_(2)-CH_(3)` and `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH_(
3)` are chain
isomer. (B) `CH_(3)-CH_(2)-NH-CH_(2)-CH_(3)` and `CH_(3)-CH_(2)-underset(NH_(2))underset(|)(CH)-CH_(3)` are funcational isomer.
(C) `H-underset(O)underset(||)(C)-O-Me` and `CH_(3)-underset(O)underset(||)(C)-OH` are funcational isomer
(D) `CH_(3)-underset(O)underset(||)(C)-CH_(3)` and `CH_(3)-CH_(2)-CH = 0` isomers.
