Solution

The correct option is C Its population growth curve is of J type
The rainy season is the favourable condition for the growth of this particular insect and so there is exponential growth. Its population growth curve is J shaped in which density increases rapidly in exponential fashion and then stops abruptly as environmental resistance or another limiting factor becomes effective abruptly.
