So firstly, remember that subtracting a negative number is the same as adding a positive number so our expression will look like this:

$-19+10+20-30+15$

Now solve as such:

$\underbrace{-19+10}_{-9}+20-30+15\\\\\underbrace{-9+20}_{11}-30+15\\\\\underbrace{11-30}_{-19}+15\\\\\underbrace{-19+15}_{-4}\\\\-4$

Your answer is -4, or A.
