The vertices of a parallelogram are plotted on the coordinate plane shown below. A coordinate grid is shown. The numbers to the left of the y-axis are negative 10, negative 8. negative 6, negative 4, negative 2, 2, 4, 6, 8, 10. The numbers below the x-axis are negative 10, negative 8, negative 6, negative 4, negative 2, 2, 4, 6, 8, 10. There are four points on the coordinate grid. What is the area, in square units, of the parallelogram?
A. 8
B. 9
C. 12
D 24.
