Write the Polynomial in Descending Order of the Variable X $5 y ^ { 4 } + 5 x ^ { 2 } + 6 x + 19 x ^ { 3 }$

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.
- $5 y ^ { 4 } + 5 x ^ { 2 } + 6 x + 19 x ^ { 3 }$

A) $19 x ^ { 3 } + 5 x ^ { 2 } + 6 x + 5 y ^ { 4 } , \text { degree } 10$
B) $5 y ^ { 4 } + 19 x ^ { 3 } + 5 x ^ { 2 } + 6 x \text {, degree } 10$
C) $5 y ^ { 4 } + 19 x ^ { 3 } + 5 x ^ { 2 } + 6 x \text {, degree } 4$
D) $$19 x ^ { 3 } + 5 x ^ { 2 } + 6 x + 5 y ^ { 4 } \text {, degree } 4$$
