Which of the following connectors can connect to both USB and Thunderbolt devices?

The choice of USB-C as the correct answer is based on its versatility and capability to support both USB and Thunderbolt devices through the same connector type. USB-C is a 24-pin connector that has become a standardized interface for many types of devices, allowing for data transfer, power delivery, and video output.

With respect to Thunderbolt, USB-C is the connector utilized in Thunderbolt 3 and Thunderbolt 4 implementations, which enables high-speed data transfer rates and the ability to daisy-chain multiple devices. This dual compatibility means that devices equipped with USB-C ports can communicate with both traditional USB peripherals and devices that advance Thunderbolt technology, as both interfaces are fundamentally compatible at the hardware level.

In contrast, the other options do not have this capability. RJ-11 is a connector primarily used for telephone lines and has no relevance to USB or Thunderbolt technologies. miniUSB is an older type of USB connector that does not support Thunderbolt connections, and SC refers to a type of fiber optic connector that is entirely different and irrelevant to both USB and Thunderbolt.
