B Correct answer
Explanation

Distance = speed * time. Speed = 3 * 10^8 m/s. Time = 1 hour = 3600 seconds. Distance = 3 * 10^8 * 3600 = 10800 * 10^8 = 1.08 * 10^12 m.

AI explanation

Using the formula Distance equals Speed multiplied by Time, we convert one hour into 3600 seconds. Multiplying the speed of 3.0 x 10^8 m/s by 3600 s gives 10800 x 10^8 m, which equals 1.08 x 10^12 m. The light will travel 1.08 x 10^12 m.
