A silent chain, also known as an inverted tooth chain, is a type of chain used in various mechanical systems. It is designed to provide smooth and quiet operation, hence the name "silent chain". The correct answer to the question is option 'C', which states that a silent chain consists of inverted tooth overlapping links.

Explanation:
Silent chains are commonly used in applications that require high-speed and high-torque transmission, such as motorcycles, bicycles, and industrial machinery. They are preferred over other types of chains because they produce less noise and vibration during operation.

Key Points:
1. Silent Chain Components: A silent chain primarily consists of inverted tooth overlapping links. These links have specially shaped teeth that interlock with each other, forming a continuous loop.
2. Inverted Tooth Design: The inverted tooth design of the links allows for smooth engagement and disengagement between the chain and sprockets. This design helps reduce noise and vibration.
3. Overlapping Links: The links in a silent chain overlap with each other, ensuring a larger contact area with the sprockets. This increased contact area enhances the chain's ability to transmit high torque efficiently.
4. Silent Chain Advantages: Silent chains offer several advantages over other types of chains. They provide smoother and quieter operation, have a higher power transmission capacity, and require less maintenance.
5. Applications: Silent chains are commonly used in motorcycles, bicycles, automotive engines, printing presses, conveyors, and various industrial machinery.

Conclusion:
In summary, a silent chain consists of inverted tooth overlapping links. This design allows for smooth and quiet operation, making silent chains ideal for applications that require high-speed and high-torque transmission.
