Solution

The correct option is C Exponential growth
Exponential growth occurs in new and sparsely inhabited environment. E. coli in a culture dish with unlimited supply of fresh media in a good environment will show exponential growth. But in the natural world, exponential growth seldom occurs since there is no such thing as unlimited supply of fresh media and the conditions are rarely favourable all the time.

Thus, in natural environment, logistic growth is more commonly observed.
