**Core Concept**
Ergonomics plays a crucial role in preventing musculoskeletal disorders, particularly in the workplace or during prolonged activities. The use of adjustable furniture, such as desks and chairs, can significantly reduce the risk of neck and back problems by promoting proper posture and reducing strain on the musculoskeletal system.

**Why the Correct Answer is Right**
A well-designed ergonomic desk with a table top can help prevent neck problems by encouraging users to maintain a neutral head and neck position. This is achieved by adjusting the height of the desk to allow the user to work with their elbows at a 90-degree angle, wrists straight, and monitor at eye level. This reduces the need for prolonged forward leaning or twisting, which can lead to muscle fatigue and strain.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not relevant to the context of preventing neck problems through ergonomic design.
* **Option B:** While ergonomic design is crucial, this option does not specifically address the use of a table top to prevent neck problems.
* **Option D:** This option is unrelated to the context of preventing neck problems through ergonomic design.

**Clinical Pearl / High-Yield Fact**
Ergonomic design principles can be applied to various aspects of daily life, including workstations, homes, and vehicles, to reduce the risk of musculoskeletal disorders.

**Correct Answer:** C.
