Question 1/127

A developer created a Visualforce page with a custom controller to show a list of accounts. The page uses the <apex:SelecList> component, with a variable called "selection", to show the valid values for Account.Type. The page uses an <apex:pageBlockTable> component to display the list of accounts, where the iteration variable is "acct". The developer wants to ensure that when a user selects a type on the <apex : selectList> component, only accounts with that type are shown on the page. What should the developer do to accomplish this?

A. Use the onChange event to update the list of accounts in the controller when the value changes, and then re-render the pageBlockTable.

B. Create multiple lists in the controller that represent the relevant accounts for each account type when the page loads, then reference the correct one dynamically on the pageBlockTable.

C. Create a component for each option and use a variable with hide parameter on the element.

D. Add the Rendered={!Acct.type==selection} attribute to the pageBlockTable component
