The correct answer is A. Compactness.
A video disk is a type of optical disc that can store digital video data. It is a flat, circular disc that is made of a thin layer of metal or plastic. The data is stored on the disc in the form of tiny pits and bumps. A laser is used to read the data from the disc.
Video disks are compact and portable, which makes them easy to store and transport. They also have a large storage capacity, which means that they can store a lot of video data. Video disks are also durable and can withstand a lot of wear and tear.
However, video disks are not as cost-effective as other types of storage media, such as DVDs and Blu-ray discs. They are also not as widely used as other types of storage media.
Here is a brief explanation of each option:
- Compactness: Video disks are compact and portable, which makes them easy to store and transport.
- Potential capacity: Video disks have a large storage capacity, which means that they can store a lot of video data.
- Durability: Video disks are durable and can withstand a lot of wear and tear.
- Cost effectiveness: Video disks are not as cost-effective as other types of storage media, such as DVDs and Blu-ray discs.
- None of the above: Video disks are not as widely used as other types of storage media.
