Question

which of the following is an example of effective feedback? \i think i understand. do you mean...?\ \you should just stop talking.\ \that doesnt make sense at all.\ \thats wrong, and heres why.\

Explanation:

Effective feedback is specific, objective, and provides reasons. "That's wrong, and here's why." gives a clear - cut statement of incorrectness along with an intention to explain the reason, which is in line with the characteristics of effective feedback. The other options are either too vague ("I think I understand. Do you mean...?"), or just a command ("You should just stop talking.") or a general criticism without explanation ("That doesn't make sense at all.").

Answer:

"That's wrong, and here's why."
