To determine which polynomial is written in standard form, we need to check if the terms are arranged in descending order according to their degrees (powers of (x)).
Let's analyze each option:
A.
Terms: () (degree 3), () (degree 6), () (degree 2), (-10) (degree 0).
Not in standard form (the highest degree term () is not first).
B.
Terms: (-10) (degree 0), () (degree 2), () (degree 3), () (degree 6).
Not in standard form (the highest degree term () is last).
C.
