Answer: C) -12
Step-by-step explanation:
Check out the number line diagram below. Zero can be thought of as the center of the number line. If you move to the right, then you are working with positive numbers (eg: 1,2,3,4,...). The more you move to the right, the larger the number gets.
If you moved in the opposite direction from 0, then we'll get a mirror copy of what's going on with the positive numbers. Something like -12 is fairly close to zero compared to something like -23 and -56.
Based on that diagram, we see that the values -43, -56 and -76 are all to the left of -23. Only -12 is to the right of -23.
