Amount at the end of 5 years = ?
Statement 1:
(1) At the end of the first year, the value of the investment is $5,100.
P(1+(2/100)) = 5100. We can get the value of P.

Hence,
sufficient Statement 2:
(2) At the end of the third year, the value of the investment is $5,306.04.
P(1+(2/100)) ^3 = 5306.04. We can get the value of P.
Using it, we can calculate the interest earned for 5 years.
Hence,
sufficient Option D
