Since chemically based life requires biological molecules to come into contact with each other, this will require a planet with
A) a strong magnetic field
B) a liquid on its surface
C) either an atmosphere to mix gases or a liquid medium on or below the surface
D) a large moon

Question

Quizplus · Accepted Answer

Chemically based life requires biological molecules to come into contact with each other, which can only occur in either an atmosphere to mix gases or a liquid medium on or below the surface. Therefore, choice C is the best option, as it explicitly states one of these requirements. A strong magnetic field (choice A) and a large moon (choice D) are not necessarily requirements for life, but may have other beneficial effects. While liquid on the surface (choice B) is necessary for some forms of life, it is not a requirement for chemically based life as there may be liquid water underground or suspended in the atmosphere.
