For this case, like terms refer to:

Equal variables in a given equation.

For example, suppose we have the following polynomial:

Like terms are:

The terms whose variables have exponent equal to 1.

We have then:

6x and 2x

the best definition for the phrase like terms is:

D) Terms that have identical variable parts.
