which type of unethical activity is sometimes caused by channel management?\na. price fixing\nb. unfair…

Answer: B. Unfair discrimination

Brief Explanations:

Channel management involves overseeing distribution channels. Unfair discrimination can occur when a channel partner is given preferential treatment (e.g., better pricing, support) over others without a legitimate business reason, which is an unethical practice linked to this area. Price fixing is typically a collusion between competitors, network marketing is a legitimate distribution model, and cold calling is a sales tactic, not an unethical issue caused by channel management.
