What is the present perfect form of "She is happy with her results"?

The present perfect form expresses an action or state that began in the past and has relevance to the present. In the case of "She is happy with her results," the focus is on her ongoing state of happiness about her results, which connects her past feelings to the present moment.

The correct answer uses "has been" to indicate that her happiness started at a specific time in the past and continues to the present. Thus, "She has been happy with her results" effectively communicates that she has experienced happiness as a state since the results were received and maintains that feeling now.

Other options diverge from this meaning. One option incorrectly employs the future perfect tense, suggesting a condition that has not yet occurred, while another option uses the present continuous tense, which implies a temporary state rather than a lasting condition. Lastly, the fourth option does not use the correct verb form to convey the state of being happy, focusing instead on the noun "happiness," which does not accurately match the original intent of the sentence.
