Refer to the figure below. Which written description is appropriately matched to the figure?
A) The behavior of primitive protocells toward molecules in the environment was likely determined by the lengths of the fatty acid tails in their membranes.
B) The origin of life most likely involved a step in which membranes formed around building block molecules that could polymerize into larger molecules.
C) The primitive protocell facilitated polymerization of larger biomolecules because its membrane allowed only small molecules to move in and out.
D) Fatty acid molecules have a polar head and nonpolar tail, which allows them to self-assemble into bilayer membranes when placed in water.
E) Primitive protocells were not self-reproducing at first, but likely evolved this capability over time.
