Which of the following is a characteristic of VGA connectors?

VGA (Video Graphics Array) connectors are designed specifically for transmitting video signals from a computer to a monitor or display. They use an analog signal, which means they are limited to only sending video information and do not support audio transmission. Therefore, the characteristic that accurately describes VGA connectors is their capability to transmit only video.

In contrast, other answers reflect features that VGA does not possess. For instance, VGA does not transmit audio and video together, nor does it support digital signals as it operates based on analog technology. Additionally, while some modern technologies can support ultra-high definition resolutions like 4K, traditional VGA connectors are limited to much lower resolutions. Thus, the focus on VGA’s exclusive ability to transmit video makes this answer precise and relevant.
