Which one of the following pairs of isomers is an example of metamerism?

Step-by-step solution

Compounds given in option ( A ) are chain isomers. Compounds given in option ( B ) are not isomers since molecular formula is not same. Compounds given in option ( C ) are position isomers. Distribution of alkyl groups around polyvalent functional group ( - O - ,   - CO - ,   - COO -  etc. ) give rise to metamers and phenomenon is called metamerism.
