Which sentence uses the present verb tense?

The sentence "He cuts the grass" uses the present verb tense because it describes a habitual action that occurs regularly in the present time. The verb "cuts" is in the simple present tense, indicating that the action of cutting the grass is something he does repeatedly or as a routine. This formation is typically used to convey facts, general truths, or ongoing actions.

In contrast, "He is cutting the grass" employs the present continuous tense, reflecting an action that is happening right now rather than a general, ongoing action. "He cut the grass" is in the simple past tense, indicating an action that has already been completed in the past. Lastly, "He was cutting the grass" is in the past continuous tense, which indicates an ongoing action that was taking place at a specific time in the past. Each of these other options illustrates different verb tenses, but only the chosen sentence maintains the simple present tense.
