Which of the following refers to the cognitive skill of breaking down complex information into smaller parts?

The correct choice is analysis, as it specifically refers to the cognitive skill of deconstructing complex information into smaller components for better understanding. This process involves examining the details and relationships within the information to grasp how the parts fit together or contribute to the whole.

In the context of learning and cognitive development, analysis is a critical skill, as it allows learners to make sense of intricate concepts, identify patterns, draw conclusions, and ultimately enhance their understanding of the subject matter.

Comprehension involves grasping the meaning of the information as a whole, rather than breaking it down into components. Knowledge pertains to the recall of facts or information without necessarily understanding the underlying structures or relationships. Synthesis involves combining different ideas or pieces of information to form a new, cohesive understanding, which is different from the act of analyzing. Thus, analysis is distinctly focused on disaggregation, making it the best choice in this case.
