How can Universal Container’s Salesforce Admin capture the company cases through a web form so that a case is created whenever someone submits information on any of their webpages?

Answer options:

A.Generate Web to Case HTML code and insert it on the company website
B.Enable the webform on the support settings
C.Create Case Escalation Rule
D.Develop a Case Trigger

Correct Answer: A 
Generating web to case HTML code and inserting it on the company website will allow the company to capture cases in a web form. So, whenever someone submits any request through the website form, a case will be created. 
Option B is incorrect because there is no option to enable the web form on the support settings. 
Option C is incorrect because case escalation rules determine when a case should be escalated. 
Option D is incorrect because case triggers define the apex triggers for cases.
