The sidereal day is defined as the time it takes for Earth to complete one rotation with respect to a distant star. This is slightly shorter than the solar day, which is the time it takes for the Sun to return to the same position in the sky, due to Earth's orbit around the Sun. The other options (equinox, synodic, zodiacal, Julian) are not directly related to the length of a day.
