Which of the following flows can execute without user intervention?

An autolaunched flow is designed to run without any user interaction. This type of flow can be invoked programmatically, for example, via Apex, Process Builder, or through a platform event, and it executes in the background as part of a larger automated process. This makes it highly versatile for automating complex business logic or various tasks within Salesforce.

Scheduled flows also run without user intervention, but their execution relies on a specific schedule set by the user, meaning they are not self-starting in the same way that autolaunched flows can be triggered dynamically. Record-triggered flows can be set to run automatically when a record is created or updated, which also allows for some level of automation, but they are specifically tied to those events and require the context of a record change to initiate. On the other hand, screen flows require direct user input to function as they involve screens that need user interaction to progress through the flow.

Thus, the defining characteristic of an autolaunched flow being able to start independently of direct user input makes it the correct choice among the options given.
