(b) Exponential growth
 
(c) Decreasing growth
 
(d) Deacceleration growth
 
The question was asked in an international level competition.

Right choice is (b) Exponential growth
 
The explanation: The stationary phase is absent in exponential growth. Exponential growth is observed when resources in the population are unlimited. The population grows in geometric fashion and results in a J-shaped curve.
