Which sentence is an example of present tense?

The sentence "She is attending training today" is an example of present tense because it uses the present continuous form, which consists of the present tense of the verb "to be" (is) followed by the present participle of the main verb (attending). This structure indicates an action that is currently in progress or happening at the moment of speaking. Present continuous is often used to describe actions occurring right now or around the present time.

In this case, "is attending" emphasizes that the training is taking place today, reinforcing the immediacy of the action in the present tense. This is distinct from the other options, which utilize different tenses, such as present perfect, simple future, and simple past.
