The three techniques that are particularly useful for avoiding conflicts using effective communication skills are using "I" language,paying attention to nonverbal cues,and:

A) to practice the art of being silent.
B) accommodating others' views.
C) communicating consequences.
D) using "you" language subtly.

Communicating consequences can help avoid conflicts by clearly stating the potential outcomes of certain actions or behaviors. This can help others understand the impact of their actions and modify their behavior accordingly. Accommodating others' views can also be helpful, but it may not always be feasible or appropriate. Using "you" language subtly can actually lead to conflicts by coming across as accusatory or blaming. While practicing the art of being silent can be helpful in certain situations, it may not always address the underlying issues and can also be interpreted as disinterest or indifference.
