Write the Polynomial in Descending Order of the Variable X $- 1 - 3 x ^ { 4 } + 7 x ^ { 5 }$

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.
- $- 1 - 3 x ^ { 4 } + 7 x ^ { 5 }$

A) descending order, degree 5
B) $7 x ^ { 5 } - 3 x ^ { 4 } - 1 , \text { degree } 9$
C) $$7 x ^ { 5 } - 3 x ^ { 4 } - 1 \text {, degree } 5$$
D) descending order, degree 10
