Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
In naming cycloalkenes, number the ring to give the double-bonded carbons $1$ and $2$ and choose the direction of numbering so that the substituents get the lowest numbers. The position of the double bond is not indicated because it is known to bond between $C - 1$ and $C - 2$ .
So, its IUPAC name is 3-methyl cyclopentene.
