How Did Phospholipids Confer an Advantage in Terms of Natural

How did phospholipids confer an advantage in terms of natural selection for vesicles that had higher phospholipid content?

A) Vesicles with higher phospholipid content could tolerate a wider range of temperatures in a warmer world.
B) Vesicles with higher phospholipid content were more efficient at transporting materials back and forth across the membrane.
C) Vesicles with higher phospholipid content tended to grow more than those with lower phospholipid content, giving higher phospholipid vesicles the ability to outcompete others.
D) Vesicles with higher phospholipid content were able to tolerate a more acidic environment that was typical of the prebiotic "soup" that existed at the time cells originated.
