Explanation:

- Principal Investment: A invests Rs12,000.

- Interest Rate: 5% per annum, compounded annually.

- Investment Duration: 2 years.

Let's calculate using the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

- A is the amount on maturity.

- P is the principal amount (Rs12,000).

- r is the annual interest rate (0.05).

- n is the number of times interest is compounded per year (1 for annually).

- t is the time the money is invested for (2 years).

$$A=12000(1+0.05/1{)}^{1\times 2}=12000(1.05{)}^2=12000\times 1.1025=13230$$

- Option 1: Rs13,230

- Option 2: Rs11,280

- Option 3: Rs12,450

- Option 4: Rs14,560
