Answer: C.

Explanation:
Given: The function
represents the growth of a ladybug population every year in a wooded area.
If Adrianne wants to manipulate the formula to an equivalent form that calculates every 3 months, not every year.

And 1 month =
year
So, 3 months =
year
So, the required function would look like :_

Hence, C is the right answer.
