The correct answer is (A)-(III), (B)-(I), (C)-(IV), (D)-(II).

Here's why:

(A) n-propanol and Isopropanol are position isomers. In n-propanol, the -OH group is at the end of the chain, while in isopropanol, the -OH group is in the middle of the chain.

(B) Methoxypropane and ethoxyethane are metamers. They have the same molecular formula but different number of carbon atoms on either side of the oxygen atom in the ether group.

(C) Propanone and propanal are functional isomers. Propanone is a ketone and propanal is an aldehyde. They have the same molecular formula but different functional groups.

(D) Neopentane and Isopentane are chain isomers. They have the same molecular formula but different arrangements of the carbon chain.
