Answer : HREF and Name
Name : The name attribute is used when sending data in a form submission. Different controls respond differently. For example, you may have several radio buttons with different id attributes, but the same name. When submitted, there is just the one value in the response - the radio button you selected.
HREF : The main use of anchor tags - <a></a> - is as hyperlinks. That basically means that they take you somewhere. Hyperlinks require the href property, because it specifies a location.
