Answer 1

If you could label the hydrophobic portion of the plasma membrane with a blue dye, you would find the blue color:

c. on the interior portion of the plasma membrane bilayer, associated with the fatty acid tails.

The hydrophobic portion of the plasma membrane refers to the fatty acid tails of the phospholipids that make up the bilayer. These tails are not associated with the polar head groups, glycocalyx, or cholesterol outside the membrane.
