What can be used to embed a component into screen flows or autolaunched flows?

The choice of using lightning:flow is correct because this component enables the inclusion of a Flow within Lightning components, making it possible to seamlessly integrate flows into both screen flows and autolaunched flows. By using lightning:flow, developers can invoke a flow and pass relevant variables to it, thereby enhancing the user experience by providing interactive capabilities directly within the context of other Lightning components.

When using lightning:flow, it is designed specifically to work with Lightning Web Components (LWC) and Aura components, which allows for more dynamic and responsive interactions. This flexibility is essential in modern Salesforce application development, as it facilitates the use of flows in conjunction with a variety of Lightning-based interfaces.

The other options are focused on different aspects of Salesforce and its components. For instance, flow:component may not be the correct choice because it does not specifically reference the correct implementation context needed for embedding flows into Lightning components. Similarly, flow:embed and lightning:componentEmbed do not align with the established method for integrating flows within the Lightning framework. Therefore, lightning:flow stands out as the appropriate component for embedding flows, as it is tailored for this particular use case.
