Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
Isomers with the same molecular formula but different alkyl groups are called metamers e.g. an ether with formula $C_{4} H_{10} O$ has three metamers viz. $C H_{3} - O - C_{3} H_{7}, C_{2} H_{5} - O - C_{2} H_{5}, C H_{3} - C H (C H_{3}) - O - C H_{3}$
