Which of the following strategies should be adopted for effective active listening? One should not ask questions even if they do not understand a message completely One should not interrupt a speaker before they are finished. One should avoid direct eye contact. One should not paraphrase a message because it always leads to misinterpretations.

Active listening implies completely giving attention to the person speaking and demonstrating authentic interest for the speaker's words. In this context, avoiding interrupting the speaker is necessary for effective active listening because this demonstrates interest and respect for the speaker. Also, by avoid interrupting one can better focus on the process of listening. Moreover, interruption in communication shows one person is more interested in speaking rather than listening. Thus, the strategy that should be adopted for effective active listening is "One should not interrupt a speaker before they are finished".
