Solution

The answer is the second one (or B): generations per time period.

Explanation for each option: a) Available nutrients - This is not constant in binary fission as nutrients can be depleted over time. b) Generations per time period - This is correct. In binary fission, the growth rate refers to the number of generations (or divisions) occurring per unit of time, which is constant during the exponential phase. c) Fertile bacterial cells - This is not a constant factor as the number of fertile cells can change over time. d) Number of initial bacterial cells - This is not constant as the initial number of cells is fixed at the start but changes as the cells divide.

Summary: The constant growth rate in the context of binary fission describes the generations per time period.
