Persuasion is considered to be an ethical intervention when a client:

A) ​solicits advice in early phases of the helping process.
B) ​contemplates actions that run contrary to his or her own goals.
C) ​questions a social worker's professional knowledge and expertise.
D) ​attempts to avoid consequences.

Persuasion can be considered ethical when a client contemplates actions that run contrary to his or her own stated goals. In this case, the social worker can use persuasion to help the client see the potential negative consequences of their actions and encourage them to choose a different course of action that aligns with their goals. However, coercion or manipulation should be avoided, and the client must ultimately make their own decisions. The other choices do not necessarily involve situations where persuasion would be considered an ethical intervention.
