Option 2 is the right answer is 
| 
means the given option is false.
The angular acceleration & angular velocity are vectors whose direction is perpendicular to the plane of the circle in which motion is occuring.
Whereas the others are are true because 
and 
are in the plane of the circle where as & are perpendicular to plane .Hence option 1 and 3 are not the answer.
Talking about the last option the is in radial direction whereas is in tangential direction.So option 4 is not the answer.
Hence the answer of the question is 2
Hope it helps!!

Three identical balls are placed on a frictionless
horizontal surface touching each other. They stick to
each other because of adhesive. Another ball of same
radius and mass m is placed over the void created by
the three balls. Find the forces applied by the balls
kept on the floor to each other if the system remains
in equilibrium.
