Which statement about pro-drop languages is incorrect according to the material?

• A. Pronouns may be omitted when they are pragmatically inferable.
• B. English is a non-pro-drop language.
• C. In commands, subject pronouns are often omitted.
• D. Pronouns must always be present in every sentence.

Answer: (D)

Pro-drop languages let pronouns be left out when who is being talked about is clear from the verb form or the surrounding context. That means pronouns can be omitted if the sentence still signals who the subject is. In commands, this omission is common because the imperative form already marks the action as directed at “you,” so an explicit pronoun isn’t needed. English, by contrast, is typically described as non-pro-drop because you usually need an overt subject in declarative sentences, though imperatives often drop the subject. The statement that pronouns must always be present in every sentence contradicts this behavior, making it the incorrect one.
