Cevap

The correct features are the reversible physical plug orientation that allows insertion in either direction, and support for Alternate Mode (Alt Mode) to transmit non-USB signals such as DisplayPort video.
The USB Type-C standard specifies a symmetrical, reversible physical connector that eliminates orientation issues when plugging in cables. Additionally, USB Type-C supports Alternate Mode (Alt Mode), allowing multiplexing of non-USB data protocols such as DisplayPort video directly across the cable pins.

Adım Adım Çözüm

1
Identify physical features of USB Type-C connectors.
USB Type-C connectors feature a symmetrical 24-pin design that allows them to be plugged in without regard to orientation.
Reversibility is a core design standard for USB Type-C physical interfaces.
2
Identify signaling and protocol capabilities of USB Type-C ports.
USB Type-C hardware specifications include DisplayPort Alternate Mode (Alt Mode) capability for video transmission.
Alt Mode enables pins within the USB Type-C connector to carry native DisplayPort or HDMI signals directly to external displays.
