Use a Sum or Difference Identity to Find the Exact $\cos 34 ^ { \circ } \sin 25 ^ { \circ }$

Use a sum or difference identity to find the exact value.
- $\cos 34 ^ { \circ } \sin 25 ^ { \circ }$

A) $\frac { 1 } { 2 } \left( \cos 59 ^ { \circ } + \cos 9 ^ { \circ } \right)$
B) $\frac { 1 } { 2 } \left( \sin 59 ^ { \circ } - \sin 9 ^ { \circ } \right)$
C) $\frac { 1 } { 2 } \left( \sin 59 ^ { \circ } + \sin 9 ^ { \circ } \right)$
D) $\frac { 1 } { 2 } \left( \cos 59 ^ { \circ } - \cos 9 ^ { \circ } \right)$
