g_scratchpad is a server-to-client data transfer object used primarily in the classic web UI rendering pipeline. A common, documented pattern is to populate g_scratchpad in a Display Business Rule (server-side) and then read those values in client-side scripts (such as Client Scripts or UI Scripts) while the form is being rendered in the browser. This avoids extra server calls when you need a small set of precomputed values or flags, such as whether the current user meets a condition, whether a related record exists, or which UI behavior should be enabled. It is not used to “populate properties for a Display Business Rule” as an end in itself; rather, the Display Business Rule is the place where developers often set g_scratchpad. It is also not a concept for defining constructors/destructors for table classes. While similar patterns can exist across experiences, g_scratchpad is specifically recognized as a web client bridging mechanism tied to server-side display processing, which matches option B.
