Answer

Explanation:

Step1: Recall standard - form of polynomial

A polynomial in one variable is in standard form when its terms are written in descending order of exponents.

Step2: Analyze option A

The polynomial (10 - n= - n+10) has terms with exponents (1) and (0) and is written in descending - order of exponents.

Step3: Analyze option B

The polynomial (5n + 3n^{3}-1=3n^{3}+5n - 1) is not in standard form as the terms are not in descending order of exponents (the exponents are (1), (3), and (0) in the given order).

Step4: Analyze option C

The polynomial (n + 4n^{2}-7n^{3}=-7n^{3}+4n^{2}+n) is not in standard form as the terms are not in descending order of exponents (the exponents are (1), (2), and (3) in the given order).

Answer:

A. (10 - n)
