Correct answers given are 1,2,3 but realm name is used only in case of BASIC authorization,so in that case how come 1 and 2 can be correct answers??

I m puzzled. Sorry, for my lack of knowledge. How can FORM (case 3) be a BASIC type also?

1,2,3 follows the DTD for login-config :
<!ELEMENT login-config (auth-method?, realm-name?, form-login-config?)>
so it's perfectly fine.
In 3, realm-name is not needed though, so it's just being ignored.
