Correct Answers: C and E 
When you create a new custom table in the Power Apps portal using a New table panel, you can select from two types of tables: Standard — this is a default custom table type user can create.
Activity — this is a special custom table type for storing activity information like appointments, phone calls, emails, tasks, etc.
There is the third table type: Virtual. This custom table type has columns that bring data from external sources, like Azure SQL Database or Azure Cosmos DB. You need to use a classic interface for the creation of the virtual table. 
All other options are incorrect.
