उत्तर
The sidereal day is shorter than the solar day by about 4 minutes.
Explanation:
A sidereal day is the time earth takes to rotate once relative to the stars, about 4 minutes shorter than the solar day because earth moves in its orbit, requiring extra rotation time for the Sun to be at the same position in the sky.
