Write the Polynomial in Descending Order of the Variable X $- 8 x ^ { 3 } - 2 x ^ { 4 } + 8 x ^ { 5 } + 12$

Write the polynomial in descending order of the variable x. If the polynomial is already in descending order, so state.
Give the degree of the polynomial.
- $- 8 x ^ { 3 } - 2 x ^ { 4 } + 8 x ^ { 5 } + 12$

A) descending order, degree 5
B) descending order, degree 12
C) $8 x ^ { 5 } - 2 x ^ { 4 } - 8 x ^ { 3 } + 12 , \text { degree } 5$
D) $8 x ^ { 5 } - 2 x ^ { 4 } - 8 x ^ { 3 } + 12 , \text { degree } 13$
