Which of the following statements about TOGAF Building Blocks and their use in the ADM cycle is correct?

As the ADM progresses, especially into later phases like Phase E (Opportunities & Solutions), architectural building blocks move from abstract conceptual definitions to more concrete, detailed, and implementation-specific components, often transforming into Solution Building Blocks.

Building Blocks evolve in their level of detail and specificity across phases, rather than evolving to a common pattern of steps.

While the Preliminary Phase establishes the architecture capability, the formal identification of abstract architectural building blocks typically begins in Phase A and subsequent phases as the architecture vision and domains are defined.

Building Blocks are identified and evolved throughout the ADM; while they are central to Phase D (Technology Architecture), conceptual blocks emerge earlier, and their selection is an ongoing process.
