Five different forces act on an object. is it possible for the net force on the object to be zero? explain

Of course it is !

-- Whatever the resultant of four of the forces is, one more force
with the same magnitude in exactly the opposite direction makes
the overall net force zero.

-- Example: 
4 cheerleaders are in a tug-of-war against the captain of the football team.
The flag in the middle of the rope is stationary.
He's holding off all 4 of the skinny girls.
The net force on the flag is zero.

Try c ? that’s what i got
