Write the product as a sum or difference of trigonometric functions.
- $8 \sin 57 ^ { \circ } \cos 110 ^ { \circ }$

A) $4 \left[ \cos 167 ^ { \circ } + \cos \left( - 53 ^ { \circ } \right) \right]$
B) $8 \left[ \cos 167 ^ { \circ } + \cos \left( - 53 ^ { \circ } \right) \right]$
C) $4 \left[ \sin 167 ^ { \circ } - \sin \left( - 53 ^ { \circ } \right) \right]$
D) $4 \left[ \sin 167 ^ { \circ } + \sin \left( - 53 ^ { \circ } \right) \right]$
