Verified by Experts
The correct answer is:
D

Analyzing the pairs of compounds in List-I:
2-Methylpropene and but-1-ene have the same molecular formula but different carbon skeletons (branched vs straight chain). Thus, they are chain isomers. (A-III)
Cis-but-2-ene and trans-but-2-ene are geometrical isomers, which fall under the category of stereoisomers. (B-I)
2-Butanol ( ) and diethyl ether ( ) have the same molecular formula but different functional groups (alcohol vs ether). Thus, they are functional group isomers. (C-IV)
But-1-ene and but-2-ene have the same carbon chain and functional group but differ in the position of the double bond (at vs ). Thus, they are position isomers. (D-II)

Matching the pairs: A-III, B-I, C-IV, D-II.
