Universal Container VP of support requested the Salesforce Admin to set up a guided wizard with a screen that pops up whenever support handles customer calls. What is the best functionality to implement this requirement?

Answer options:

A.Process Builder
B.Flow Builder
C.Workflow Rule
D.Approval Process

Correct Answer: B 
Flow Builder gives Salesforce admins the ability to build a guided wizard with screens. It has many out of the box screen components. In addition to this, you can build custom components and add them to it. 
Options A, C, and D are incorrect because they lack the ability to have a guided wizard with screens. They don’t have visual representation like the flow.
