Answer:
B. Dismissing someone's concerns as unimportant
Step-by-step explanation:
You are avoiding their point of view, thus it could be equated to a cold shoulder strategy. Wouldn't be D or C because that's solving the conflict, and A doesn't necessarily mean that you are completely avoiding their explanation.
Cold Shoulder - reject or be deliberately unfriendly to.
You are rejecting someone's beliefs.
Hope this helps!
