The correct answer is b. Slipping.<br /><br />Brown dust on the air conditioner compressor clutch typically indicates that the clutch may be slipping.

This can lead to excessive heat buildup and wear on the clutch components, resulting in the brown dust. It is important to have the clutch inspected and repaired or replaced if necessary to ensure proper operation of the air conditioning system.
