✔ Answer: Not listed? Wait — let's check options:

But in the image, options for Q7 are not shown, so we can't choose yet.

But based on calculation:

$$
-5 - 16 = -21
$$

So if the choices were:
A) -21
B) 21
C) -11
D) 11

Then answer would be A) -21

But since options aren’t visible in your image, I’ll assume they exist.
