Final answer:
The types of passive adapters that enable DVI-to-HDMI connectivity are DVI-D to HDMI and DVI-I to HDMI as they both support digital signals required for HDMI compatibility.
Step-by-step explanation:
To determine which types of passive adapters enable DVI-to-HDMI connectivity, it's important to understand the differences between DVI connectors. There are several types of DVI connectors, but the ones that are compatible with HDMI, which carries a digital signal, are:
- DVI-D to HDMI - This adapter is compatible because DVI-D carries a digital signal, which can be directly translated to HDMI without any conversion.
- DVI-I to HDMI - DVI-I includes both digital and analog signals. The digital portion of DVI-I is compatible with HDMI, so a passive adapter can connect DVI-I to HDMI by using only the digital signal.
The option DVI-A carries an analog signal, which is not directly compatible with the digital HDMI signal without an active conversion process, thus DVI-A to HDMI adapter won't be a passive but rather an active adapter. Therefore, the correct answers are options A (DVI-D to HDMI) and C (DVI-I to HDMI), allowing for a passive adapter connection from DVI to HDMI.
