Final Answer :
A
Explanation :
Polarized gladhands are designed to prevent the incorrect connection of the trailer supply and service hoses by having different configurations, ensuring that each hose is connected to the correct coupling. Technician B's statement about quick release gladhands is incorrect; their purpose is not related to faster emergency brake applications but to allow for quick and easy connection and disconnection of air lines.
