Write the Complex Number in Trigonometric Form R(c $$r ( \cos \theta + i \sin \theta )$$

Write the complex number in trigonometric form r(c $$r ( \cos \theta + i \sin \theta )$$ ) , with $$\theta$$ in the interval [0 $$\left[ 0 ^ { \circ } , 360 ^ { \circ } \right)$$
- $- \sqrt { 7 } - i \sqrt { 7 }$

A) $\sqrt { 14 } \left( \cos 225 ^ { \circ } + i \sin 225 ^ { \circ } \right)$
B) $\sqrt { 14 } \left( \cos 315 ^ { \circ } + i \sin 315 ^ { \circ } \right)$
C) $\sqrt { 14 } \left( \cos 135 ^ { \circ } + i \sin 135 ^ { \circ } \right)$
D) $\sqrt { 14 } \left( \cos 45 ^ { \circ } + \mathrm { i } \sin 45 ^ { \circ } \right)$
