Acell spends approximately 90% of its cycle in
m phase
s phase
interphase
g0 phase

The correct answer is interphase.

The interphase is the longest phase of the cell cycle. it is estimated that the cell spends most of its life in interphase, which covers approximately 90 percent of the cell cycle. In the interphase, the cell grows and prepare for the mitosis, the amount of the DNA is also doubled in S phase, which is a part of interphase only.
