Answer:
Option A.
Step-by-step explanation:
In order to write any polynomial in standard form, we need to check the degree of each term, then write each term in order of degree, from highest to lowest, left to right.
The given polynomial is

Here, the combine degree of x and y in each term is 4.
If we arrange the terms according to the degree of x, then

If we arrange the terms according to the degree of y, then

Hence, the correct option is A.
