What approach should an app builder take to show Component as a related list on Product?
A . Create a master-detail relationship on Product to Component. Add the Component related list to the Product page layout.
B . Create a junction object to relate Component and Product. Add the Component related list to the Product page layout.
C . Create a roll-up on Product. Add the Component related list to the Product page layout.
D . Create a lookup relationship on Component to Product. Add the Component related list to the Product page layout.

Answer: D

Explanation:

To show Component as a related list on Product, a lookup relationship on Component to Product should be created. A lookup relationship creates a loose association between two objects and allows users to relate records from one object to another. A lookup relationship also allows users to add the related list of the child object to the parent object’s page layout.
