Imagine another solar system, with a star more massive than the Sun. Suppose a planet with the same mass as Earth orbits at a distance of 1 AU from the star. How would the planet's year (orbital period) compare to Earth's year?
A) The planet's year would be shorter than Earth's.
B) The planet's year would be longer than Earth's.
C) The planet's year would be the same as Earth's.
D) An orbit at a distance of 1 AU would not be possible around a star more massive than the Sun.

A more massive star exerts a stronger gravitational force, which increases the orbital speed of the planet. Therefore, the planet would complete its orbit in a shorter time, resulting in a shorter year compared to Earth's.
