The polynomial written in standard from is -7xy³ - 3x³y + 8x²y² + 4x².
The standard form of a polynomial is expressed by writing the highest degree of terms first then the next degree and so on.
In other words the terms are arranged by decreasing order of degrees.
The degree of a polynomial is the exponential value of the variables.
Therefore, the polynomial written in standard from in the options is as follows:
-7xy³ - 3x³y + 8x²y² + 4x²
