PLZ HELP!! what best describes a phospholipid bilayer?

a. their chemical formula is (CH2O)n
(the n might be a typo but that's how the teacher wrote it)
b. they form cell membranes
c. they are proteins
d. they are ionic​

B. They form cell membranes

Explanation:

There's not really an explanation, that's just a fact. A phospholipid bilayer has two layers of, yep, phospholipids. They stay together well and kind of move around a little, allowing small particles to pass through. There are some proteins in them also that help them function as cell membranes.
