A Public Sector Organization (PSO) is seeking to improve how they manage its community grants...

A (Enable Chatter); C (Migrate Users to Lightning Experience); E (Customer Community Plus Licenses). This is the lowest-customization answer that still satisfies the business, security, and lifecycle requirements.

The Core Concept Explained: Experience Cloud design is driven by persona, authentication, scale, and sharing. The wrong template or license can create unnecessary cost, weak security, or excessive customization.

Step-by-Step Technical Analysis: Begin with the external persona, authentication requirement, and transaction volume. Select the Experience Cloud license or template that matches that access pattern, then configure sharing sets, external OWD, site visibility, and page access. Finish by testing the experience as anonymous, authenticated, and internal users. Enable Chatter, migrate staff to Lightning Experience, and procure Customer Community Plus licenses for grant-seeker portal users.

Why the Incorrect Options Are Wrong: B does not meet the implementation-quality bar for security, scale, auditability, or maintainability in this scenario. D adds a custom build path and increases lifecycle, security, and upgrade effort when a packaged or declarative capability already supports the requirement.
