Which connector is Apple's proprietary interface for iPhone and iPad accessories?

• A. USB-C
• B. Lightning
• C. HDMI
• D. DisplayPort

Answer: (B)

Lightning is Apple's proprietary interface for iPhone and iPad accessories. It was designed as a small, reversible connector used for charging and data transfer, replacing the older 30-pin dock. Because it’s Apple-specific, third-party accessories must go through Apple’s licensing (the MFi program) to work with iOS devices. This distinguishes it from standard connectors like USB-C (a universal standard), HDMI, or DisplayPort, which are not proprietary to Apple. (Note: Apple has since begun shifting toward USB-C on newer models in response to regulatory changes, but Lightning remains the traditional Apple accessory connector.)
