C Correct answer
Explanation

Ole Rømer was the first to measure the speed of light in 1676 by observing Jupiter's moon Io. He noticed that the timing of Io's eclipses varied depending on Earth's distance from Jupiter, allowing him to calculate light's finite speed. Galileo and Newton contributed to optics but didn't measure light speed. Einstein's work came much later.
