Hi. You didn't provide the answer options, which makes it impossible for me to answer your question specifically. However, I will try to help you as best I can.
One way Imelda can use interpersonal communication would be when she explains that she can't help her coworker because she's too busy, but she can help him when finishing her activities if he still needs help.
This is a way to show that she has the domain of interpersonal communication, because interpersonal communication is that established between two people, where each person can include their experiences and occupations in the communication process, even personal and emotional information can be presented. In this way, when Imelda informs her co-worker that she will not be able to help him because she is busy, she demonstrates mastery of interpersonal communication.
