Answer:
D
Step-by-step explanation:
The correct option would be D.
12 - 2 would give +10
-5 + 5 would give 0
-5(-2) would give +10
24 - 34 would give -10
Hence, options A, B, and C are incorrect because they give figures that deviate away from -10. The only option whose operation results to -10 is D.
