Answer :

The Earth orbits around the sun in a path that takes approximately one year to complete. This period is what defines a year and is based on the time it takes for the Earth to make one complete revolution around the sun. Here is a brief explanation of each option: - One month: This is the approximate amount of time it takes for the moon to orbit the Earth, not the amount of time it takes for the Earth to orbit the sun. - One hour: This is a unit of time that represents 60 minutes; it has no direct correlation with the Earth’s orbit around the sun. - One day: This is the amount of time it takes for the Earth to complete one full rotation on its axis, not its orbit around the sun. - One year: This is the time it takes for the Earth to make one full orbit around the sun, which is what defines a year. Therefore, the answer to the question "Which is equal to one Earth orbit around the sun?" is "one year."
