Final answer:

Phospholipids are characterized by their hydrophilic heads and hydrophobic tails, which enable them to form the bilayer structure of cell membranes.

Step-by-step explanation:

The correct answer to the question “Which of the following is true of phospholipids?” is C. Have hydrophilic heads. Phospholipids are essential components of cell membranes and exhibit a unique structure with hydrophilic (water-attracting) heads and hydrophobic (water-repelling) tails. The phospholipid molecule is composed of a glycerol molecule connected to two fatty acid chains (the hydrophobic tails) and a phosphate group (the hydrophilic head). These components allow phospholipids to organize into a bilayer, with heads facing the aqueous environment and tails facing inward, away from water, thus creating the fundamental structure of the plasma membrane.
