djyliett [7]

Answer:

Option A. is correct

Step-by-step explanation:

For example 2x^3,7x^3 are like terms and 5x^2,9x^5 are unlike terms.

Given polynomial is 3x^3+x^2-8x^5+2x^3-4x

Like terms need to be combined to write the polynomial in standard form

Here, like terms are 3x^3,2x^3

Option A. is correct.
