Answer:
a change in elevation from 632 feet to 312 feet
Last option
Step-by-step explanation:
When change is modeled by a negative number, there must be a decrease from the first value to the second value.
The second elevation must be less than the first.
In your options - first to second values:
492 => 783 Increased 492 < 783
-12 => 123 Increased -12 < 123
0 => 87 Increased 0 < 87
632 => 312 Decreased 632 > 312
Sea level is "0" because it's where you start measuring elevation.
