Which sentence uses the simple present to describe routine?

• A. The dog barks every morning.
• B. The dog barking every morning.
• C. The dog barked every morning.
• D. The dog will bark every morning.

Answer: (A)

Describing routines in English uses the simple present. When something happens regularly, we use the base verb and add -s for third‑person singular subjects like “the dog,” giving “barks.” The phrase “every morning” signals a repeating habit, so “The dog barks every morning” expresses a habitual action. The form with “barking” isn’t correct here because it’s a present participle and would need an auxiliary like “is” to form the present continuous, which describes an action happening right now, not a routine. “Barked” is past tense, and “will bark” is future, neither of which expresses a current routine.
