Perform the Operation and Leave the Result in Trigonometric Form $$\frac { 2 \left( \cos 70 ^ { \circ } + i \sin 70 ^ { \circ } \right) } { 4 \left( \cos 40 ^ { \circ } + i \sin 40 ^ { \circ } \right) }$$

Perform the operation and leave the result in trigonometric form.​ $$\frac { 2 \left( \cos 70 ^ { \circ } + i \sin 70 ^ { \circ } \right) } { 4 \left( \cos 40 ^ { \circ } + i \sin 40 ^ { \circ } \right) }$$ ​

A) ​ $\frac { 1 } { 2 } \left( \cos 30 ^ { \circ } + i \sin 30 ^ { \circ } \right)$
B) ​ $\frac { 1 } { 2 } \left( \cos 40 ^ { \circ } + i \sin 40 ^ { \circ } \right)$
C) ​ $\frac { 1 } { 2 } \left( \cos 30 ^ { \circ } - i \sin 30 ^ { \circ } \right)$
D) ​ $\frac { 1 } { 2 } \left( \cos 70 ^ { \circ } - i \sin 70 ^ { \circ } \right)$
E) ​ $\frac { 1 } { 2 } \left( \cos 70 ^ { \circ } + i \sin 70 ^ { \circ } \right)$
