Which two scenarios are ideal for using Appian Portals?

Appian Portals are designed for scenarios where users who do not have an Appian account need to interact with Appian applications. This makes them ideal for public-facing applications such as surveys (Option B) or for allowing external users to initiate processes like registrations (Option C). They are not intended for internal use by employees (Option A) or for scenarios requiring offline capabilities (Option D).
