The correct answer is: B.It halts the cell cycle at the G1 phase.

Explanation:

In the absence of nutrients, cells are unable to proceed with division because they lack the necessary resources for growth and replication. The G1 phase is particularly sensitive to nutrient availability, and under nutrient deprivation, the cell cycle is often halted at this phase. This prevents the cell from entering the S phase (DNA replication) and further stages of the cycle, ensuring that the cell doesn't divide when it lacks the resources to support division.
