$A.$ Population density after time $t$
$B.$ Population density at time zero
$C.$ Intrinsic rate of natural increase
$D.$ The base of natural logarithms $(2.71828)$
Identify $A, B, C$ and $D$ from the given equation
Change in population size equation with prolonged exponential phase can be converted into logistic growth equation by multiplying it with
