The answer is in the options 3 and 4.
Because when the block is about to touch the spring the energy stored in it is purely kinetic.
Its kinetic energy is given by K.E=
When it touches the spring the spring gets compressed and its kinetic energy gets converted into potential energy.That is the block does some work to compress the spring through a distance ‘x’ which is equal to 
When the block is in equilibrium position the net force on the block is zero and its kinetic energy is zero and potential energy is equal to its total energy

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.
