Correct option is (a) True

The explanation: In the jolt method of ramming, impact force is generated by the application of overhead hopper, this impact force compact the sand uniformly in the mould. This is achieved by continuous lifting and dropping of hopper and then the required hardness is achieved by the mould. Horizontal surfaces are mostly compatible or preferred for the optimization of this method.
