Multiple Choice

Find the derivative of y with respect to the appropriate variable.
- $$y = \left( \theta ^ { 2 } + 4 \theta \right) \tanh ^ { - 1 } ( \theta + 3 )$$

A) $( 2 \theta + 4 ) \tanh ^ { - 1 } ( \theta + 3 ) - \frac { \theta } { \theta + 2 }$
B) $( 2 \theta + 4 ) - \frac { 1 } { \theta + 8 }$
C) $( 2 \theta + 4 ) \tanh ^ { - 1 } ( \theta + 3 ) - \frac { \theta ^ { 2 } + 4 \theta } { 1 + ( \theta + 3 ) ^ { 2 } }$
D) $- \frac { \theta } { \theta + 2 }$
