Explanation:
SQL injection and Cross Site scripting attacks are the top two risks on the OWASP list.
The top risks identified by the Open Web Application Security Project (OWASP) group as of 2013 are as follows:
A1: Injection

Injection flaws, such as SQL, OS, and LDAP injection occur when untrusted data is sent to an interpreter as part of a command or query.
A2: Cross-Site Scripting (XSS)

A3: Broken Authentication and Session Management

A4: Insecure Direct Object References

A5: Cross-Site Request Forgery (CSRF)

A6: Security Misconfiguration

A7: Insecure Cryptographic Storage

A8: Failure to Restrict URL Access

A9: Insufficient Transport Layer Protection

A10: Unvalidated Redirects and Forwards

Incorrect Answers:
A: OWASP refers to SQL, OS, and LDAP injections, not to Dynamic Unicode injection.
C: Weak Authentication and Session Management attacks are ranked third on the OWASP list.
D: Security Misconfiguration is ranked third on the OWASP list.
