A,B,D
Correct answer
Explanation
Declare Expressions, Edit Validate, and When rules are declarative or decision rules in Pega. They support the "Build for Change" philosophy by externalizing business rules and calculations from procedural code, making them easy to update. Rule-File-Text is simply a static file container and does not directly support this design principle.
