Find the Quotient and Write in Rectangular Form $\frac { 12 \left( \cos 240 ^ { \circ } + i \sin 240 ^ { \circ } \right) } { 3 \left( \cos 60 ^ { \circ } + i \sin 60 ^ { \circ } \right) }$

Multiple Choice

Find the quotient and write in rectangular form. First convert the numerator and denominator to trigonometric form.
- $\frac { 12 \left( \cos 240 ^ { \circ } + i \sin 240 ^ { \circ } \right) } { 3 \left( \cos 60 ^ { \circ } + i \sin 60 ^ { \circ } \right) }$

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