The Correct Option is C

Solution and Explanation

We are asked whether the smallest term deposit is less than ₹2.5 crore. From the question, we know that the average size of the three term deposits is ₹3 crore. This means the sum of the three term deposits is: \[ \text{Sum of deposits} = 3 \times 3 = 9 \text{ crore} \] Statement I:
- The highest term deposit is ₹3.9 crore.
This statement alone doesn't provide enough information to determine if the smallest deposit is less than ₹2.5 crore. We only know the highest deposit, but we don't know how the remaining two deposits compare.
Statement II:
- There are two more term deposits other than the highest term deposit, and one of them is ₹2.1 crore.
From this, we know one deposit is ₹2.1 crore. Since the sum of all three deposits is ₹9 crore, the third deposit (the smallest one) must be: \[ \text{Smallest deposit} = 9 - 3.9 - 2.1 = 3 \text{ crore} \] Thus, the smallest deposit is ₹3 crore, which is not less than ₹2.5 crore.
Since we need both statements together to conclude that the smallest deposit is not less than ₹2.5 crore, the correct answer is (3).
