When you need to communicate a large amount of information on a topic, the best medium to choose often depends on the nature of the content, the preferences of the recipient, and the context in which the information will be consumed. However, the list below provides a general guide to which medium might be most appropriate for various scenarios:

a) Audio recordings can be useful for conveying information that doesn't require visual aids to understand. They are convenient for users who are on the go or prefer to listen rather than read or watch content. Examples include podcasts, audiobooks, and lectures.

b) Video is a versatile medium that can combine visual aids, text, and audio to create a comprehensive learning experience. Video can be particularly effective when the information involves demonstrations, visual examples, or when it's important to capture the audience's attention through dynamic content.

c) Text is a traditional and effective medium for conveying large amounts of detailed information. It allows readers to process information at their own pace, review sections easily, and refer back to the information later. Text is suitable for complex topics that require deep focus or may need to be referenced in a searchable format, such as academic papers, extensive reports, and legal documents.

d) Photos alone are typically not sufficient for giving someone a lot of information on a topic unless the subject is primarily visual, such as photography or art. In most cases, photographs would need to be accompanied by text or other media to sufficiently convey detailed information.

For most educational or informative purposes, combining elements from multiple mediums—such as a video with text subtitles or an article with embedded audio clips and relevant images—can enhance understanding and retention of the information. Multimedia presentations, infographics, and interactive content can also be very effective for engaging an audience while delivering complex information.
