Option A is right.

Given that:

Mean = 1700

Standard deviation = 100

So, the range for 3 standard deviations to the right and to the left of the mean is:

[tex]\left(1700-3\left(100\right)\ ,\ 1700\ +\ 3\left(100\right)\right)\\=\left(1700-300,\ 1700\ +\ 300\right)\\=\left(1400,\ 2000\right)[/tex]
