Question restatement: A compound composed of carbon, hydrogen and oxygen with three fatty acids attached to a molecule of glycerol would be known as a

Answer options:
- a. triglyceride.
- b. diglyceride.
- c. monoglyceride.
- d. phospholipid.

Now, evaluating each option:

Option a: Triglyceride. This is the correct classification for a glycerol backbone bound to three fatty acid chains (three acyl groups), forming a triacylglycerol. This structure is the most common form of stored fat in organisms and matches the description exactly.

Option b: Diglyceride. A diglyceride has two fatty acid chains attached to glycerol. Since the description specifies three fatty acids, this option is inconsistent with the given structure and is therefore incorrect.

Option c: Monoglyceride. A monoglyceride has only one fatty acid attached to glycerol. This does not fit the description of three fatty acids on glycerol, so this option is also incorrect.

Option d: Phospholipid. Phospholipids typically have two fatty acid chains attached to glycerol plus a phosphate-containing head group. While they involve glycerol and fatty acids, the presence of three fatty acids as described would not align with a standard phospholipid structure, making this choice unsuitable for the description provided.

In summary, the description precisely matches a triglyceride, while the other options describe structures with fewer fatty acids or a different functional group arrangement. The key distinction lies in the number of fatty acid chains attached to the glycerol backbone and the typical functional group composition of the molecule.
