It is essential that every student ______ on time.

Answer and explanation

Correct answer: A. arrive

  1. Step 1: The sentence uses an impersonal adjective construction expressing necessity or urgency ("It is essential that..."). Such mandative clauses trigger the present subjunctive mood in formal English.
  2. Step 2: The present subjunctive uses the base (bare infinitive) form of the verb for all persons and numbers regardless of third-person singular subjects. The base form of "arrive" is "arrive".
Answer
arrive.
