Which options are valid technology choices for video conferencing?

The selection of FaceTime and Skype on a mobile phone represents valid technology choices for video conferencing because both applications are specifically designed to facilitate video communication. FaceTime, developed by Apple, allows users to make video calls over Wi-Fi or cellular networks, offering a user-friendly interface that integrates seamlessly with iOS devices. Skype, which is cross-platform, provides video calling capabilities along with additional features like screen sharing and group video calls, making it a robust tool for virtual meetings and communication.

In contrast, the other options do not specifically focus on video conferencing. For example, Microsoft Word and Google Docs are primarily text-editing and document collaboration tools, lacking video communication features. Similarly, Apple Photos is designed for viewing and organizing images, while iMovie is focused on video editing, and neither supports real-time video conferencing. PowerPoint is a presentation software that does not include video call functionality either. Thus, option B stands out as the correct choice for technologies aimed at video conferencing.
