To find the area of a triangle, we can decompose it into two smaller right triangles.
Each of the right triangles has a base of 5 units and a height of 10 units.
Therefore, the area of Triangle C = 2 * (1/2 * base * height) = 2 * (1/2 * 5 * 10) = 2 * 25 = 50 square units.
Therefore, the correct answer is not listed above, as the actual area of Triangle C is 50 square units.
