Answer:
The type of function that represents this pattern is:
Option: C)
C.) Exponential growth.
Explanation:
It is given that the number of mice living in a field triples each year.
This means that the population of mice is increasing at a constant rate i.e. 3 each year.
So, the function that represent this pattern is a exponential growth.
Also let P(t) be the function that represents the population of mice after 't' years.
Then P(t) is modeled as:

where
is the initial population of the mice.
Hence, Option: C is the correct answer.
C) Exponential Growth.
