b = False
c = False
if a or b and c:
         print "HELLO"
else:
         print "hello"

HELLO

Hello

HellO

None of these

Explanation

The correct answer is:

(A) HELLO

The expression a or b and c evaluates the logical conditions.
Python evaluates and before or. So, the expression is evaluated as a or (b and c).
Since b and c is False (because both b and c are False), the condition becomes a or False, which is True or False, which results in True.
Since the condition is True, the if block is executed, and it prints "HELLO".
