What is the main advantage of conditional statements in SQL injection attacks?
A. They allow the attacker to perform blind SQL injection attacks when the output of the query is not visible or
error messages are suppressed
B. They allow the attacker to perform union-based SQL injection attacks when the original query and the
injected query have different number or type of columns
C. They allow the attacker to perform error-based SQL injection attacks when the database server returns
detailed error messages or stack traces
D. They allow the attacker to perform time-based SQL injection attacks when the database server supports
time-delay functions or commands
