Please select which statement is the most accurate:

Agile is a broad mindset and a set of values and principles for software development, as outlined in the Agile Manifesto. It is not a specific methodology itself. Scrum is a lightweight framework that helps teams implement the Agile mindset. It provides a defined structure of roles, events, and artifacts to put Agile principles into practice. Therefore, Scrum is one of the most popular implementations of Agile development.

A. This inverts the relationship. Agile is the overarching philosophy; Scrum is a framework that adheres to that philosophy.
C. This is the same statement as option B, but written in Portuguese, making it redundant in an English-language context.
D. They are not synonyms. Agile is a set of principles, while Scrum is a specific, prescriptive framework for enacting those principles.
E. They are not contrasting. Scrum is fundamentally based on and aligned with the values and principles of Agile development.

3. Layton, M. C. (2012). Agile Project Management For Dummies. John Wiley & Sons. Chapter 1, "Introducing Agile Project Management," explains that Scrum is a specific method under the Agile umbrella. (Note: While a commercial book, its foundational explanation is widely accepted and mirrors academic definitions).
