Final answer:

Storage lipids like triglycerides have three fatty acids ester-linked to a single glycerol, forming a hydrophobic molecule used for energy storage. The correct option is B.

Step-by-step explanation:

The structural features possessed by storage lipids, specifically triglycerides, are: B. Three fatty acids ester-linked to a single glycerol. This structure forms a hydrophobic molecule that is used by many organisms as an energy-storage molecule.

In contrast, phospholipids have two fatty acids attached to a glycerol backbone along with a phosphate-containing group, making them amphipathic due to their hydrophobic tails and hydrophilic head groups.
