d.
the account had an initial balance of $2,500 and compounds daily at an annual interest rate of 2.1%.

D

Step-by-step explanation:

If we look at the formula for compound growth and learn what each variable represents, we can solve this problem very easily.

The formula is:

Compound Growth >>  

Where

F is the Future Amount (accumulated amount after certain years)

P is the Initial Balance (principal amount)

r is the rate of interest (given in decimal)

n is the number of compounding (if 2, compounded semi annually, 4 means compounded quarterly, 52 means compounded weekly, and 365 means compounded daily)

t is the time in years

Now, the formula given is:

Comparing this with compound growth formula, we see that:

Now, looking at the answer choices, we see that D is the correct choice.
