Parts of the following sentence have been given as options. Select the option that contains an error.
She didn't went to the party because she was feeling sick.

Correct option is D

Option (d) contains an error. The phrase "She didn't went" improperly uses the past tense verb "went" after the auxiliary verb "did," which is grammatically incorrect.
The auxiliary "did" is already in the past tense, so the main verb should be in its base form, "go," to correctly form the past simple negative structure. Thus, the correct phrase should be "She didn't go."
· Grammatical rule used: In English, when forming the past simple negative, "did not" (didn't) is followed by the base form of the main verb.
· Example: She didn't like the movie.
