A = -599 if I read the question correctly
Hello There!

is in standard index form.
Standard form is when it is the original number
The '-5' as a power means you need to shift the zero back 5 spaces.
Or, divide by 100,000.
If you do this, you would get
0.000087.
Thus, making it option
B.
Hope This Helps You!Good Luck :)
