Which statement describes a characteristic of digital cameras?

• A. They require film development.
• B. They use light-sensitive cells to capture images.
• C. They are primarily designed for video recording only.
• D. They can operate without any power source.

Answer: (B)

Digital cameras are characterized by their use of light-sensitive cells, such as CCD (Charge-Coupled Device) or CMOS (Complementary Metal-Oxide-Semiconductor) sensors, to capture images. These sensors convert the light from the scene into electrical signals, which are then processed to create a digital image. This is a fundamental aspect of how digital cameras function, contrasting with traditional cameras that rely on the chemical reaction of film for image capture. The other statements do not accurately describe digital cameras. Film development is specific to analog cameras, and some digital cameras do have video recording capabilities, but they are not exclusively designed for video. Lastly, while digital cameras require a certain power source, often in the form of batteries or other rechargeable options, they cannot operate without power.
