The figure shows a typical bacterial growth curve, consisting of four stages: lag, exponential (log), stationary, and death. During the lag phase (stage A), cells are adapting to their new environment and are not actively dividing, but they are alive and may be synthesizing new enzymes or taking up nutrients. In the exponential phase (stage B), cells are actively dividing and growing exponentially. In the stationary phase (stage C), cell growth slows and the number of new cells produced equals the number of cells that die, resulting in a plateau in cell numbers. In the death phase (stage D), cells start to die at an accelerating rate. Therefore, statement D is correct: cells are alive but not reproducing during the stage represented by A.
