Question 27:
A section of a Visualforce page that allows users to enter input and then submit it with an <apex:commandButton> or <apex:commandLink>. The body of the form determines the data that is displayed and the way it is processed. It`s a best practice to verify that pages and custom components use at most one <apex:form> tag. As of API version 18.0, this tag can`t be a child component of <apex:repeat>.
Answer options:
A. apex:form B. apex:chart C. apex:actionRegion D. apex:insert
