You are the business analyst for your organization and are working with Virginia on the allocation of requirements for a new solution. You have assigned Virginia the task of breaking down the solution

Incorrect because decision analysis involves evaluating and comparing options or courses of action to support decision-making, not breaking down a scope into smaller components.

Incorrect because business rules analysis focuses on identifying and defining the rules that govern organizational decisions, not decomposing solution scope into sub-components.

Incorrect because process modeling creates visual representations of the steps and flow within a business process, which is distinct from decomposing a solution scope into allocable components.

Functional decomposition specifically involves systematically breaking down a larger scope, system, or function into progressively smaller sub-components until the pieces are manageable enough to assign and analyze. In this scenario, Virginia is decomposing the solution scope into smaller components for requirements allocation, which exactly matches the purpose and process of functional decomposition. This technique is a core BABOK tool used during solution scoping and requirements structuring.
