Answer: D.)  16 units

Step-by-step explanation:

The y-values are the same, so the coordinates lie on a horizontal line.

Find the difference between the x-values.

-21 -(-5) = -16   Subtracting a negative is like adding a positive.

-21 + 5 =  -16   The distance is an absolute value, so disregard the negative sign.
