Question

Which following best express this population

Answer 1

I'm pretty sure it is (B)

Answer 2

If you round the given number to the nearest thousand, you get 1,703,000. This will then convert to
`1.703 * 10^6` when you convert to scientific notation. The '6' tells us to move the decimal point 6 spots to the right to get 1,703,000 back again.

So this is why the answer is choice B.
