Answer - B - To fix the hidden node problem, you should move the hidden node station within transmission range of the other stations.

Key Takeaway: The hidden node problem arises when client stations cannot hear the RF transmissions of another client station. Increasing the transmission power of client stations will increase the transmission range of each station, resulting in increased likelihood of all the stations hearing each other. Moving the hidden node station within transmission range of the other stations also results in stations hearing each other.
