   A canvas app uses a Dataverse table with 100,000 records. The app has a gallery that displays records where the Status field equals 'Active'. The gallery's Items property is: Filter(Table, Status = 'Active'). The Monitor tool shows that the query is delegated, but the gallery still loads slowly. You need to improve performance. What should you do?

   • AAdd an index on the Status column in Dataverse and ensure the gallery uses a view that filters on Status.
   • BIncrease the data row limit in the app settings to 2000.
   • CUse the Monitor tool to check if the query is truly delegated, then change the filter to use a different column.
   • DPre-load all active records into a collection in OnStart and filter the collection.
