Which verb tense indicates continuing action?

A. Present
B. Past perfect
C. Future
D. Progressive

I see two that could be correct answers.

Past perfect verbs indicate an action that started in the past and continues into the present.

Progressive verbs indicate an action that is on-going.

The verb tense that indicates continuing action is the progressive tense, which is option D.

To determine the progressive tense, you need to look for the auxiliary verb "be" followed by the main verb in the present participle form (-ing form). This combination shows that the action is ongoing or continuous.

For example, in the sentence "She is running," the word "is" is the auxiliary verb "be," and "running" is the present participle form of the main verb "run." Together, they create the present progressive tense, indicating that the action of running is happening now and is ongoing.

In contrast, the present tense (option A) refers to actions that are happening now but may not necessarily be continuous. The past perfect tense (option B) denotes actions or events that were completed before a specific point in the past. The future tense (option C) refers to actions that are yet to happen.
