What type of connector does Thunderbolt 3 use?

  1. USB Type-A

  2. MDP

  3. HDMI

  4. USB Type-C

The correct answer is: USB Type-C

Thunderbolt 3 uses a USB Type-C connector. USB Type-A (Option A) and HDMI (Option C) are incorrect because they do not support the high data transfer speeds required for Thunderbolt 3. MDP (Option B) is also incorrect because it stands for Mini DisplayPort, which is a different type of connector. USB Type-C (Option D) is the correct answer because it supports the high data transfer speeds and other features required for Thunderbolt 3 connectivity.
