**Answer: (4) 3 years**

**Explanation:-
**Let the time is t years.

Principal Rs,3375, Amount = Rs.4096 & Rate = 20/3 %

Then, Compound Interest = 4096 – 3375

= Rs.721

4096 = 3375(1 + 20/3 x 100)

4096 = 3375(1 + 1/15)

4096 = 3375(16/15)

4096/3375 = (16/15)

(16/15)

Comparing on both side,

t = 3 years

Hence, the answer is (4) 3 years.
