Answer 12

Correct answer: c

Explanation:

The GoTo command is used for unconditional jumping to different portions of a PL/SQL block.

If-Then-Else statement will not allow you to jump to another section of a PL/SQL block. It first checks the condition, i.e., whether it is 'TRUE' OR 'FALSE' and accordingly executes the statement. Thus, choice A is incorrect.

Choice B is incorrect because all loops are simply iterative statements.

Choice D is incorrect because Decode function cannot be used in a PL/SQL block as it decodes an expression in an SQL statement similar to the IF-THEN-ELSE loop.
