The following sentence has been split into four segments. Identify the segment that contains a grammatical error.
She always / invite me / to / dinner.

Correct option is D

The segment that contains a grammatical error is "(d) invite me."

The verb "invite" should be in its third-person singular form, which is "invites," because the subject "she" is third-person singular and requires the verb to agree with it.

Grammatical rule used: In the present simple tense, a third-person singular subject (he, she, it) requires the verb to take an "-s" or "-es" ending.

Example: She always invites me to dinner.
