A Correct answer
Explanation

Light takes approximately 1.26 seconds to travel from the Moon to Earth, given the average distance of 384,400 km and lights speed of 299,792 km/s. This varies slightly due to the Moons elliptical orbit - at perigee (closest) its about 1.26 seconds, while at apogee (farthest) its roughly 1.36 seconds. Option A correctly states 1.26 secs as the typical value.
