Answer:
C. [tex]-3x^8y^2+9x^2y+10x^2[/tex]
Step-by-step explanation:
We are asked to choose the polynomial that is written in standard form.
We know that a polynomial is written in standard form, when it is written in descending order of degrees that is from highest degree to lowest degree.
Upon looking at our given choices, we can see that option C is the correct choice as it is written in descending order of degrees.
