Option: 1

Curve 'A' shows exponential growth, represented by equation \frac{dN}{dt}= rN


Option: 2

curve 'B' shows logistic growth, represented by equation \frac{dN}{dt}= rN\left ( \frac{K-N}{K} \right )


Option: 3

Exponential growth curve is considered as more realistic than the logistic growth curve


Option: 4
