This question explores something known as exponential growth, and is often used to determine compound interest after a period of time.

We can use equation

y = xr^n

Where y is the value after n years, x is the initial value and r is the percentage growth each year.

By substituting

1462 * 1.03^10

We get a value that rounds to 1965, so your answer is D.

I suggest you look at exponential growth and decay on khanacademy, they explain it very well!
