The velocity of light was first measured by

Answer & Solution
Correct Answer: Option C
The velocity of light was first measured by Romer. The first measurements of the speed of light using completely terrestrial apparatus were published in 1849 by Hippolyte Fizeau (1819–96). Compared to values accepted today, Fizeau's result (about 313,000 kilometres per second) was too high, and less accurate than those obtained by Rømer's method.
