Titan is roughly the same size as Mercury, yet Titan has an atmosphere while Mercury does not. How can this be?
A) Although Titan is roughly the same size as Mercury, it is much denser, making its gravitational field stronger
B) Unlike Mercury, Titan is constantly being bombarded by icy comets that evaporate and maintain its atmosphere
C) On its surface, Titan has volcanism that is constantly replenishing its atmosphere while Mercury does not
D) Even though Titan's gravity is weak, it is much colder, allowing molecules to be trapped in its atmosphere
