A proprietary connector used by Apple for connecting devices.

• A. USB-C
• B. MagSafe
• C. Thunderbolt
• D. Lightning

Answer: (D)

Lightning is Apple’s own connector designed for iPhone and iPad to charge and transfer data. It’s a small, reversible 8‑pin interface that Apple kept as a proprietary standard for years, which is why it’s described as Apple’s connector. The other options are not proprietary to Apple: USB-C is a universal standard used across many brands; Thunderbolt is a high-speed interface that typically uses USB-C in its modern forms but isn’t itself Apple’s unique connector; MagSafe is primarily a magnetic power connection used on Macs (and for some accessories), not the general device‑to‑cable port for iPhones and iPads.
