C is correct. Null value will always goes to 'ELSE' part. You can avoid thus by adding NVL.

A is correct answer, because condition v_myage <11 will be FALSE, and control will go to ELSE statement and output value.

If condition v_myage < 11 is NOT true, (i.e. ELSE or NULL), then control will go to ELSE clause. At this time, variable v_myage is holdng NULL value. So, above condition is NOT true, and control will move to ELSE part.
