Which of the following is a playing surface ?

Question

Accepted Answer

The correct option is (3):
Teraflex is the correct answer because it is a globally recognized brand name for a specific type of synthetic sports flooring. This material is a high-performance PVC (vinyl) surface that is engineered for indoor sports halls, making it a legitimate playing surface. It is widely used for events in sports such as volleyball, badminton, basketball, and handball, offering crucial benefits like superior shock absorption to protect athletes' joints, excellent vertical deformation for energy return, and anti-slip properties for safety. Its resilient nature and consistent ball bounce ensure fair and high-quality play, which is why it is often chosen for professional and Olympic-level competitions.

The incorrect option is (1):
Cybax is not a playing surface. This term is likely a slightly misspelled reference to **Cybex**, which is a leading brand and manufacturer of high-end strength training, cardio, and rehabilitation fitness equipment. These are machines, such as ellipticals or weight stacks, that are *used* in a gym or training facility. They are placed *on* a floor, but they do not constitute the playing surface itself.

The incorrect option is (2):
Polymetric is either an obscure term or a confusion with **Plyometric**. Plyometrics refers to a specific type of exercise training, such as jumping, hopping, or bounding, designed to increase explosive power and rate of force development. It is a training *method* or *category of exercise*, not a material or physical surface that one plays on. Therefore, it cannot be classified as a playing surface in the context of the question.

The incorrect option is (4):
Coal is incorrect because it is a sedimentary rock primarily used as a fossil fuel for heat and electricity generation. While historical sports fields might have sometimes used crushed cinders (ash residue from coal), pure coal itself is fundamentally unsuitable as a playing surface. It is abrasive, lacks any shock-absorbing quality, would create excessive dust and mess, and would be extremely unsafe for athletes to fall on, thereby ruling it out as an acceptable option.
