A Correct answer
Explanation

Binary (Bi means two) fission produces only two daughter cells and occurs repeatedly, generation after generation, in short time intervals. This fast reproduction is possible only under favourable conditions of temperature, food and humidity. But under unfavourable conditions like high or low temperature, low humidity or lack of food, multiple fission occurs.
