Answer 1

To reduce the noise of the bedroom door he should Option (b) apply the lubricants in the door joints.

Explanation:

• Lubricant is defined as the substance used to reduce friction and wear of the surfaces when they are in mutual contact with each other.
• Door hinges more often interact with the atmosphere, therefore they may get corroded.
• Due to this corrosion, the surface turns irregular, and the friction increases.
• Therefore, applying lubricant may reduce the friction and further reduce the noise while opening and closing.
