Question

shows which type of isomerism?

• A. Position isomers
• B. Chain isomers
• C. Functional isomers
• D. Metamers

Answer 1

The correct option is A Position isomers

As we can see, $-C{H}_3$ group differs in position with respect to other $-C{H}_3$ group on principal skeleton. Thus, 2-methyltoulene (o-xylene) and 4-methyltoulene (p-xylene) are position isomers of each other.
