We want to see what the numbers on the number line represent. We will see that the correct option is A:

"220 feet below sea level and 19 feet above sea level."

So we know that the surface of the river is at -220ft in the number line, and 19ft represents the top of a building.

We also know that the 0 in the number line is the sea level.

To go from 0 to -220ft, we need to move in the negative range, so we can see that "-220ft" must represent a value that is below the 0, meaning that the "-220ft" represents 220 feet below sea level (remember that the sea level is at 0).

The opposite case is for 19ft, it is in the positive range, then it is above the sea level.

Then the correct option is A:

"220 feet below sea level and 19 feet above sea level."
