He created one of the following units of time.
- Lustrum
- Leap year
- Tropical year
- Planck time
Correct Answer

A. Leap year

Explanation

A leap year is a unit of time that was created to account for the extra time it takes for the Earth to complete one orbit around the Sun. It occurs every four years and adds an extra day to the calendar year. This adjustment is necessary because the Earth's orbit is not exactly 365 days, but approximately 365.25 days. By adding an extra day every four years, we can keep our calendars aligned with the Earth's orbit and ensure that seasons occur at the same time each year.
