Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Organic compounds which have same molecular formula but different structural formula also show different chemical and physical properties, known as isomers.
Isomerism: Organic compounds are represented by using their molecular and structural formula which shows the number of bonded atoms and their skeleton. There are many organic compounds which have different properties but the same molecular formula. Such type of molecules which have the same molecular formula but different molecular structures are known as isomers of each other and this phenomenon is known as isomerism.
