Your company has an Azure subscription named Sub1 that is associated to an Azure Active Directory (Azure AD) tenant named contoso.com. The company develops a mobile application named App1. App1 uses the OAuth 2 implicit grant type to acquire Azure AD access tokens. You need to register App1 in Azure AD. What information should you obtain from the developer to register the application? 

Answer options:

A. a redirect URI
B. a reply URL
C. a key
