SAFe defines seven core competencies that enable business agility. One of these is Agile Product Delivery, which focuses on building a customer-centric approach to defining, developing, and releasing valuable solutions.

This competency emphasizes Design Thinking, DevOps, continuous delivery, and release on demand to ensure fast, high-quality value delivery aligned with customer needs. While Built-in Quality is a foundational SAFe principle, it is not categorized as a core competency.

From SAFe guidance:

''Agile Product Delivery is a customer-centric approach to defining, building, and releasing a continuous flow of valuable products and services to customers and users.''

Therefore, the correct answer is B. Agile Product Delivery, as it is one of SAFe's official seven core competencies.
