Explanation

In the IIS W3C Extended Log Format, fields appear in a fixed order: client IP, username, date, time, service/instance (W3SVC2), server name (SERVER), server IP (172.15.10.30), time taken in ms (4210), bytes sent (125), bytes received (3524), service status code (100), Windows status code (0), HTTP method (GET), and target URI. The service status code is the 11th field, which is 100. This is analogous to an HTTP 100 Continue response. Choice A is the service instance, B is the time taken, and C is the bytes received.
