Express the Area of the Region Bounded by the Given $y = x ^ { 2 }$

Express the area of the region bounded by the given line(s) and/or curve(s) as an iterated double integral.
-The parabola $y = x ^ { 2 }$ and the line $y = - 8 x + 20$

A) $\int _ { 0 } ^ { 2 } \int _ { 20 } ^ { - 8 x + x ^ { 2 } } d y d x$
B) $\int _ { - 10 } ^ { 2 } \int _ { x ^ { 2 } } ^ { - 8 x + 20 } d y d x$
C) $\int _ { - 10 } ^ { 2 } \int _ { 0 } ^ { - 8 x + 20 - x ^ { 2 } } d x d y$
D) $\int _ { 0 } ^ { 2 } \int _ { x ^ { 2 } } ^ { - 8 x + 20 } d y d x$
