Selected Answer: D
The application specifies which field is incorrect (e.g., "Username is incorrect" or "Password is incorrect"). Once he knows valid usernames, Calvin can use this information for social engineering attacks, such as phishing or other techniques to manipulate users into revealing further sensitive data.
