To execute an XXS attack, the attacker needs to inject malicious code into the website by exploiting vulnerabilities in the website's input validation mechanism. Option B states that the website accepts user input without validating it, which makes it easier for an attacker to inject malicious code and execute an XXS attack. Options A and D mention that the website validates user input, making it difficult for an attacker to inject malicious code. Option C states that the website does not accept user input without validating it, thus eliminating any possibility of an XXS attack.
