Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
A typical cell cycle comprises of interphase and mitotic phase. The interphase is the longest phase and mitotic phase is the shortest phase. Interphase comprises of the first growth phase, synthesis phase, and second growth phase. The mitosis comprises of prophase, metaphase, anaphase, telophase. The cell prepares itself for the division during interphase so it is longer than the mitotic phase.
So, the correct answer is option B.
