Answer: Option E, in 12 years.
Explanation:
A geometric growth model is characterized by its finite growth rate, known as lambda. The size of the population after a unit of time has passed can be calculated using the last known size and lamba as:

Starting from the initial value of population, the next one will be calculated multiplying by 1.4, and the next one multiplying again by 1.4, thus we can define a function that relates the time passed in year to the size of the population:

Substituting our values we get the function that defines the growth of our poupulation:

Then, we just have to clear the t that gives a population of 500:

Thus, at 12 years, the population will be greater than 500.
Lymphocytes generated during an initial infection that circulate in the body for years and quickly destroy that infection if it ever appears again are called the Memory t cells. These cells are a subset of infection that have previously encountered and responded to their respective antigen, thus they may be called the antigen experienced t cells.
