Universal Container* decides to use purely declarative development to build out a new Salesforce application. Which two options can be used to build out the business logic layer for this application?

Validation Rules are a fundamental declarative tool for enforcing data integrity and business logic by preventing users from saving records that do not meet specified criteria.

Remote Actions involve JavaScript calling Apex methods from Visualforce, which is a programmatic approach, not purely declarative.

Record-Triggered Flows are powerful declarative automation tools that execute logic automatically when a record is created, updated, or deleted, enabling complex business process automation without code.

Batch Jobs (Batch Apex) are programmatic solutions written in Apex for processing large numbers of records asynchronously, and thus are not declarative.
