Which of the following BEST mitigates the risk of SQL injection attacks against applications exposed...

Other options:

SQL server hardening (B)improves security but does not specifically address SQL injection.

Patch management (C)is necessary but does not provide immediate protection against new SQL injection attacks.

Physical controls (D)are unrelated to application-layer threats like SQL injection.
