Universal Container sales department would like to set up a new lightning home page. How can Salesforce admin build this page?

Answer options:

A.Access the page layout and add the required fields
B.Access home page component through setup to build it
C.Access Home page layout and assign it to the required profiles
D.Access the setup through lightning and then search for lightning app builder

Correct Answer: D 
You can access the Lightning App Builder from Setup by entering Lightning App Builder in the Quick Find box and then selecting Lightning App Builder. 
With the Lightning App Builder, you can build: Single-page apps that drill down into standard page, Dashboard-style apps such as apps to track top sales prospects or key leads for the quarter, point apps to solve a task, such as an expense app for users to enter expenses and monitor expenses they’ve submitted. In addition to this you can build custom record pages for your objects, tailored to the needs of your users and custom Home pages containing the components and features that your users use most. 
Other options are incorrect because they are related to salesforce classic features.
