Answer
Brief Explanations:
In English grammar, in the simple present tense, we add -s or -es to the end of a verb only when the subject is third - person singular (he, she, it, or a singular noun). For example, "He runs", "She eats". First - person singular (I), second - person plural (you), and third - person plural (they) do not require this addition.
Answer:
D. Third person singular
