Orbital period of the planet
(Earth days) 390 260

A.
The star close to planet Y has more mass.
B.
The star close to planet Y has less mass.
C.
The star close to planet Y is hotter.
D.
The star close to planet Y is cooler.

A. The star close to planet Y has more mass.
This can be inferred because the orbital period of planet Y is shorter than that of planet X, indicating that the gravitational pull of the star close to planet Y is stronger. This suggests that the star close to planet Y is more massive than the star close to planet X.
