Answer 2

The correct answer is OPTION C: Mercury.

• Mercury is our Solar System's smallest and has the shortest distance from the Sun.
• The shortest journey around the Sun takes 87.97 Earth days.
• Mercury has an odd orbit around the Sun.
• It is tidally bound to the Sun in a 3:2 spin-orbit resonance, which means that it rotates three times per two revolutions around the Sun.
• In a revolving frame of reference, it appears to rotate just once every two Mercurian years.
• As a result, every two Mercurian years, a Mercury watcher would see only one day.
