Which sentence is written in future tense?

• A. She will visit the museum tomorrow.
• B. She visits the museum tomorrow.
• C. She visited the museum yesterday.
• D. She is visiting the museum tomorrow.

Answer: (A)

Future tense shows actions that will happen later. The form to signal this is will + base verb. In the sentence with will visit, the verb pair indicates something that will occur tomorrow, so it expresses a future action. The other sentences use different tenses: visits uses the present simple to describe regular or general actions; visited is past tense describing something that happened yesterday; is visiting is present continuous, used for an action happening now or a planned arrangement, but it isn’t the simple future tense. So the sentence with will visit is the one written in future tense.
