Alexander Oparin Hypothesized That Living Cells Evolved from Coacervates

Alexander Oparin hypothesized that living cells evolved from coacervates.What was the "boundary" material of Oparin's coacervates,and how does it compare with that of most living cells?

A) Oparin's coacervates had a phospholipd bilayer,which is also found in most living cells.
B) Oparin's coacervates were surrounded by a tight skin of water molecules,which is also found in most living cells.
C) Oparin's coacervates were surrounded by carbohydrates and lipids,while most living cells are surrounded only by carbohydrates.
D) Oparin's coacervates were surrounded by a tight skin of water molecules,while most living cells have a phospholipid bilayer.
E) Starch was the main component in Oparin's coacervate boundry,while most living cells have boundaries composed only of lipids.
