Best answer
Correct answer is (a) CSS ON/Images ON

To explain I would say: CSS ON/Images On technique is also known as FIR or “Fahrner Image Replacement”. The premise here is to use a span to wrap the text inside the header and use that span to hide the text. It works but we have to use display:none.
