C. Beginning of autumn
Explanation:
On this image we can see the position of the Earth toward the Sun in four different parts of the year. WE can see that in one part of the year the Northern Hemisphere is tilted toward the Sun, while in the opposite part of the year it is the Southern Hemisphere that is tilted toward the Sun. In between them, we have 21 March and 23 September when both hemispheres are equally exposed to the sunlight. These to dates mark the beginning of spring and beginning of autumn.

Answer AND Explanation:
Exponential phase is the phase during which growth is rapid. The growth rate is proportional to the amount of material or number of cells of the organism already present. This rapid growth is due to:
- An increase in number of cells dividing following a geometric progression.
- Cells having adjusted to the new environment.
- Food and other factors are not limiting hence cells are not competing for resources.
- The rate of cell increase being higher than the rate of cell death.
