Solution

The correct option is D Generating high-frequency voltage
A Van de Graaff Generator is a machine which uses a moving belt to accumulate very high electrostatic voltages on a hollow metal sphere. This creates a large electric field which is used to accelerate charged particles. It was invented in 1929 by American physicist Robert J. Van de Graaff. The Van de Graaff generator was developed as a particle accelerator for research.
