You need to remove a custom table from an unmanaged solution. 
Please select the two component types you need to resolve before you can delete a table.

Answer options:

A.Administrative
B.Internal
C.Required
D.System
E.Dependent

Correct Answers:C and E 
Application Lifecycle Management (ALM) includes the governance, development, and maintenance of applications. The ALM application to the Power Apps, Power Automate, and Dataverse specifies the following concepts: Solution — the package of the components that can be distributed between environments.
The Dataverse`s role — the main storage of all artifacts, including the solution. All Power Platform environments following the ALM must use the Dataverse database.
Source Control — using source control management tools for storing the solutions’ and components` descriptions and code.
The solution is a file that can include various components, like tables, fields, apps, site maps, flows, etc. These components are extensions or/and modifications of the Dataverse database. Developers can create these extensions, package them, and distribute them as solutions. There are two types of solutions: unmanaged and managed. 
Unmanaged solutions are modifications that developers create in the development environment. When you need to remove the custom component from an unmanaged solution, you need to assess the component’s dependencies. You can select the component in a solutions browser, like a Customer table (Number 1), and click on the “Show dependencies” button in the top menu (Number 2). 

The Power Apps portal opens a new screen with the Dependencies for the Customer table. The screen is divided into two sections: the Dependent components (Number 1) and the Required components (Number 2). You cannot remove a component from an unmanaged solution, like the Customer table, before resolving the dependency of the other components on the component that you want to remove. 

All other options are incorrect.
