If You Determine the Number of Days in a Year

If you determine the number of days in a year with solar time and sidereal time how would they vary?

A) A year measured in sidereal time would be about 15 minutes different than a solar day, so the difference only accumulates over time.
B) A year measured in sidereal time would be about one day longer than a year based on solar time.
C) They wouldn't; a year is always about 365 1/4 days, and the 1/4 day is taken up with leap years.
D) A year measured in sidereal time would be about one day shorter than a year based on solar time.
