How can a Salesforce admin enable case feed in their new Salesforce organization that was created in May 2019?

Answer options:

A.Case feed is automatically enabled in Salesforce
B.Case Feed is enabled through case settings
C.Case Feed is enabled through support processes
D.Case Feed is enabled through feed filters

Correct Answer: A 
Case feed is automatically enabled in Salesforce after the winter’14 release. Orgs that are created before the winter’14 release are enabled through the case support settings through checking the enable the case feed action and feed items. 
Option B is incorrect because the Salesforce org has been created recently so the case feed will be automatically enabled and won’t need to be enabled through the case settings. 
Option C is incorrect because the support process works with the record type and different status picklist to streamline a support team workflow. 
Option D is incorrect because feed filters limit the types of feeds shown in the feed.
