 B) Incorrect. While proper data validation contributes to a better user experience by preventing errors, its absence does not enhance user experience.\
 C) Correct. Without proper data validation, web applications are vulnerable to SQL injection attacks, where attackers can manipulate database queries by injecting malicious SQL code.\
 D) Incorrect. Data validation helps maintain data integrity, but its absence does not improve data integrity*.

 B) Correct. Escaping user input before displaying it helps mitigate XSS attacks by rendering any potentially malicious scripts harmless, thereby preventing them from executing in users' browsers.\
 C) Incorrect. Storing user passwords in plaintext is a security risk and unrelated to preventing XSS attacks.\
 D) Incorrect. Disabling HTTPS encryption exposes sensitive data to interception and does not prevent XSS attacks.

 B) Correct. Employing input sanitization and parameterized queries helps prevent SQL injection attacks by ensuring that user input is treated as data rather than executable code, thus neutralizing malicious SQL injection attempts.\
 C) Incorrect. Storing sensitive data in plain text increases the risk of data exposure but does not directly prevent SQL injection attacks.\
 D) Incorrect. Disabling error messages may hide potential vulnerabilities from attackers but does not address the root cause of SQL injection vulnerabilities.
