Solution

The correct option is B Tubulin
Gap 2 phase, or Growth 2 phase, is the third sub phase of interphase in the cell cycle directly preceding mitosis. $G_{1}$ phase specifically stores ATP and enzymes, while histone protein is synthesized in S phase and tubulin synthesis begins in $G_{2}$ phase.
So, the correct option is 'D'.
