Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Electric locomotives use compressed air for several auxiliary systems.
Step 1: The compressor produces compressed air.
Step 2: Compressed air is required for operating air brake systems.
Step 3: It is also used for horns and sanders.
Step 4: Sanders use compressed air to spread sand on rails to improve adhesion. Therefore, the compressor provides air for: \[ \boxed{\text{Air brakes, horns, and sanders}} \]
