ANS:A - If a is true and b is true then the output is 'A && B'

Option C is correct. The output is 'ELSE'. Only when a is false do the output lines after 11 get some chance of executing. Option A is wrong. The output is 'A'. When a is true, irrespective of the value of b, only the line 5 output will be executed. The condition at line 7 will never be evaluated (when a is true it will always be trapped by the line 12 condition) therefore the output will never be 'A && B'. Option B is wrong. The output is 'A'. When a is true, irrespective of the value of b, only the line 5 output will be executed. Option D is wrong. The output is 'notB'.
