How can a Salesforce user be able to view the specific dashboard on their home page?

Answer options:

A.Import Dashboard
B.Dashboard Component
C.Dashboard Snapshot
D.Home Page Customization

Correct Answer: C 
Users can customize their home pages. The generic home page will only display a snapshot that shows the top row of the dashboard. If you go to Personal Setup -> My Personal Information -> Change My Display -> Home -> Customize My Pages (button) -> You’ll arrive at the settings for Dashboard Snapshot Component. You can then select which Dashboard components you want to have displayed on your home page. 
Option A is incorrect because the import dashboard option doesn’t exist in Salesforce. 
Option B is incorrect because a dashboard component can be a chart, table, metrics or visual force pages. 
Option D is incorrect because you can customize the home page to have sidebars, links or custom component.
