What is the purpose of presentation software?

The purpose of presentation software is to create visual aids for presentations. This type of software is specifically designed to help users develop visual content that can enhance their oral presentations, making them more engaging and effective. Presentation software allows users to incorporate various multimedia elements such as text, images, graphs, charts, and videos, which can help convey information clearly and keep the audience's attention. This tool is commonly used in business environments, educational settings, and various other scenarios where conveying ideas and information visually plays a crucial role in communication.

Other options like storing large databases or analyzing data pertain to database management systems or data analysis tools, which have different functions focused on processing and managing data rather than creating presentations. Conducting online transactions is related to e-commerce platforms, which also do not involve the creation of visual presentation materials. Thus, the primary distinction lies in its specific goal of enhancing presentations, making option B the appropriate choice.
