Find the Quotient and Write in Rectangular Form $$\frac { 16 \left( \cos 240 ^ { \circ } + i \sin 240 ^ { \circ } \right) } { 4 \left( \cos 60 ^ { \circ } + i \sin 60 ^ { \circ } \right) }$$

Multiple Choice

Find the quotient and write in rectangular form. First convert the numerator and denominator to trigonometric form.
- $$\frac { 16 \left( \cos 240 ^ { \circ } + i \sin 240 ^ { \circ } \right) } { 4 \left( \cos 60 ^ { \circ } + i \sin 60 ^ { \circ } \right) }$$

A) $- 4 \mathrm { i }$
B) $- 2 \sqrt { 3 } - 2 i$
C) $- 4 - 4 i$
D) $- 4$
