When building and using custom screen components in Salesforce Flow, there are several key considerations:

A. Correct — Custom Lightning components used in Flow run only in Lightning Runtime (not Classic).

B. Correct — Custom components can be created by developers or installed from AppExchange.

D. Correct — Screen components are only supported in Screen Flows, not Auto-Launched Flows.

Incorrect Options:

C. The "Use Lightning Components" checkbox was deprecated; it is no longer required in newer versions of Flow.

E. Visualforce is a legacy technology and not used to distribute Lightning-based Screen Flows.

Reference Extracts from Salesforce Process Automation Study Guide:

“Custom screen components are supported only in Screen Flows and run in Lightning Runtime.”

“You can install screen components from AppExchange or build your own using Lightning Web Components.”
