B Correct answer
Explanation

Both compounds are ethers with molecular formula C4H10O. Diethyl ether (C2H5-O-C2H5) and methyl isopropyl ether (CH3-O-CH(CH3)2) differ only in the alkyl groups attached to the oxygen atom. This is metamerism - a type of structural isomerism where the functional group remains the same but the alkyl groups on either side vary.
