Polynomial equation </h3>
Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign.
In the above polynomial equation the variable are<em> x </em>and <em>y </em>and the highest power of the variable <em>x</em> is four and highest power of the variable <em>y</em> is three.
Arrange the polynomial equation in the power of the variable <em>x. </em>Thus,

Arrange the polynomial equation in the power of the variable <em>y. </em>Thus,

From the given option the option A matches correctly with the above polynomial equation which is,

Thus the option A is the correct option.
