(A)-(I), (B)-(II), (C)-(III), (D)-(IV)

(A)-(IV), (B)-(II), (C)-(III), (D)-(I)

(A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Correct Answer:

(A)-(II), (B)-(IV), (C)-(I), (D)-(III)

Explanation:

 Maxwell : added displacement current to the electric current term in Ampère's Circuital Law.

G. Marconi – In 1895, G. Marconi used radio waves to transmit signals over a distance of several kilometers. He developed the technology in subsequent years to achieve greater range.

J.C Bose: He is well known for his work on the wireless transmission of information using microwaves.

Heinrich Hertz:  demonstrated the existence of the waves predicted by Maxwell by producing radio waves in his laboratory.
