Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
Multiple fission is that type of asexual reproduction in which the parental body divides into many daughter cells simultaneously during the unfavorable conditions to increase the chances of survival of daughter cells. In this, the reproductive unit is whole parental body. However, the chances of survival are quite less.
Thus, the correct answer is option (A).
