Which HDMI type allows validation of the connection with the display?

The correct answer is HDMI Digital Content Protection, also known as HDCP. This technology is designed specifically to prevent the unauthorized copying of digital content as it travels across connections like HDMI. When a device with an HDMI output connects to a display with an HDMI input, HDCP establishes a secure pathway for the transmission of content by validating that both devices support HDCP compliance.

This validation process involves the source device checking with the display for the presence of a valid HDCP key, thus ensuring that the content is protected from piracy while being transmitted. If the connection is not HDCP compliant, the video or audio content may not be transmitted, thus reinforcing the role of HDCP in maintaining content protection.

The other options do not provide this functionality related to validating connections for content protection. While HDMI Type C refers to a specific form factor of the HDMI connector, and High-Resolution HDMI is not a standardized term, Standard HDMI simply refers to the basic HDMI specifications without any specific mention of content protection or validation features. Therefore, HDCP is specifically designed to handle content protection and validation, making it the correct choice.
