A Visualforce page is written with the following controller and extensions.
<apex:page standardController=”Account” extensions=”myExtension”>
<apex:inputField value =”(!account.name)”/><p/>
<apex:commandButton value =”Save” action=”(!save)”/>
</apex:page>
The extension class myExtension has a public save() method.
Which save method or methods will be used by the Visualforce page?

 

Ans: the save method from the standardController
both – myExtension first, then the standardControllermeet
the save method from the controller extension
both – the standardController first, then myExtension

please let me know correct answer.
