Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In chain isomerism, or skeletal isomerism, components of the (usually carbon) skeleton are distinctly re-ordered to create different structures.
Hence, from the figure we can see that Butanol and 2- methyl propanol are chain isomers because they have same molecular mass and atoms but They differ in the length of carbon chain.
Hence, both assertion and reason are CORRECT and reason is the CORRECT explanation of the assertion.
