Explanation

To enable access to a new web app (App2) via a new URL (https://app2.contoso.com) through the existing Application Gateway, you need three components: (1) A new listener - configured for the hostname app2.contoso.com on HTTPS port 443, to distinguish App2 traffic from App1 traffic; (2) A new backend pool - pointing to App2's servers/instances, since App2 is a different application than App1; and (3) A new routing rule - to connect the new listener to the new backend pool so requests for app2.contoso.com are forwarded to App2's backend. Option B (listener + rule) is missing the backend pool. Option D (listener + backend pool) is missing the routing rule. Option A (backend pool + routing rule) is missing the listener. All three components are required, making C correct.
