  Hence, option (a) is incorrect. 
• Hydroelectric power is based on conversion of gravitational potential energy into electrical energy.
  Hence, option (b) is incorrect. 
• Computers are based on digital logic of electronic circuits while electric generator on Faraday's laws of electromagnetic induction.
  Hence, option (c) is correct.
• Nuclear reactor is based on controlled nuclear fission and sonar on reflection of ultrasonic waves.
  Hence, option (d) is incorrect.

The concept of antiparticle was first introduced theoretically by Paul Dirac in 1930.

Sir C.V. Raman got Nobel prize for Raman effect, which deals with scattering of light.

• Photocells are based on the Photoelectric effect of light.
• Rocket propulsion is based on Newton's law of motion and not on the laws of thermodynamics.
• Optical fibres are working according to the important property of light which is a total internal reflection of light.
• The fusion test reactor is functioning with magnetic confinement of the plasma. The fusion test reactor was a popular experiment related to magnetic plasma.
