Subtract the Polynomials $$\left( 2 x ^ { 2 n } - 7 x ^ { n } - 19 \right) - \left( 9 x ^ { 2 n } - 5 x ^ { n } + 13 \right)$$

Multiple Choice

Subtract the polynomials. Assume all variable exponents represent whole numbers.
- $$\left( 2 x ^ { 2 n } - 7 x ^ { n } - 19 \right) - \left( 9 x ^ { 2 n } - 5 x ^ { n } + 13 \right)$$

A) $- 7 x ^ { 2 n } - 2 x ^ { n } - 6$
B) $- 7 x ^ { 2 n } + 2 x ^ { n } - 6$
C) $- 7 x ^ { 2 n } - 2 x ^ { n } - 32$
D) $- 7 x ^ { 4 n } - 2 x ^ { 2 n } - 32$
