Answer
True
Work Step by Step
In logistic model, the population must be equal to carrying capacity $C$. Furthermore, the solution of logistic model can expressed as:
$$P(t)=\frac{Cp_0}{P_0+(C-P_0)e^{-rt}}$$
If we take the limit of the model.
$$limP(t)=C$$
we can see that it approaches the carrying capacity. Since the carrying capacity is constant and the derivative is the rate of change, the rate of change should be $0$.
Hence, the statement is true.
