Scenario: A Citrix Engineer is asked to implement multi-factor authentication for Citrix Gateway. The engineer creates the authentication policies and binds the policies to the appropriate bind points. The engineer creates a custom form using Notepad++ to format the page which will capture the user’s credentials.
What is the first step the engineer must perform to assign this form to the authentication process?
To assign a custom login form to the authentication process in Citrix Gateway, the first step is to create a login schema profile and select the uploaded file. This profile will determine the appearance and behavior of the login page, including the custom form created by the engineer.
C is correct. Policies and bindings are already done as specified in scenario. New login schema profile (A - is nonsense) with new login form must be created to be used by policy label

Why not C?
I've had to do this quite a few times. nFactor breaks a lot of basic stuff such as EULA.
Create a login schema profile and select the uploaded file.
