Let $a$ And $b$ Be Real Numbers A) $\int _ { - \infty } ^ { 2 } \frac { 9 } { x ^ { 2 } + 10 } d x$

Let $a$ and $b$ be real numbers. What integral must appear in place of the question mark "?" to make the following statement true?
$$\int _ { - \infty } ^ { a } \frac { 10 } { x ^ { 2 } + 9 } d x + \int _ { a } ^ { \infty } \frac { 10 } { x ^ { 2 } + 9 } d x = ? + \int _ { b } ^ { \infty } \frac { 10 } { x ^ { 2 } + 9 } d x$$

A) $\int _ { - \infty } ^ { 2 } \frac { 9 } { x ^ { 2 } + 10 } d x$
B) $\int _ { b } ^ { - \infty } \frac { 10 } { x ^ { 2 } - 9 } d x$
C) $\int _ { - \infty } ^ { b } \frac { 10 } { x ^ { 2 } + 9 } d x$
D) $\int _ { b } ^ { - \infty } \frac { 10 } { x ^ { 2 } + 9 } d x$
E) none of these
