Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Alternation of generation may be defined as a phenomenon whereby, in the life history of an organism a diploid asexual phase and a haploid sexual phase regularly alternates with each other. This type of true alternation of generation is also called metagenesis. In coelenterates an asexual polypoid generation appears to alternate regularly with a sexual medusae generation.
So, the correct answer is 'Both Assertion and Reason are correct and Reason is the correct explanation for Assertion'.
