Answer:
Logarithms are used to model all sorts of things, especially growth and decay!
Step-by-step explanation:
One super-relevant example of how logs are used is in tracking the progress of the coronavirus. There are graphs up on worldometer that show both the linear number of cases and deaths and the log numbers - why? Because this gives us a better idea of when the curve will really flatten, or when it will reach its carrying capacity.
It's also used in things like radioactive decay, or where the growth rate is not constant.
SOLUTION
The question simply means that we should find the sum to infinity of the geometric series.
The formula of sum to infinity of a geometric serie is given by

Where

So, this becomes

Therefore, option b is the correct answer
