Question restatement: This is a picture of the most common type of lipid in your body. The fat has a glycerol backbone bonded to three fatty acids. This molecule is called...

Option A: TUFA, triple unsaturated fatty acid
- This term is not the standard name for a lipid with a glycerol backbone attached to three fatty acids. It suggests a specific fatty acid composition (triple unsaturated), but the diagram describes a triacylglycerol with three fatty acids esterified to glycerol, not a single fatty acid type. Therefore, this choice mislabels the molecule and is not correct.

Option B: triglyceride
- This is the correct descriptor for a molecule with a glycerol backbone linked to three fatty acids via ester bonds. In biology, triacylglycerol (also called triglyceride) is the most common lipid stored in adipose tissue and the molecules depicted in typical diagrams show three fatty acid chains attached to a glycerol backbone. The phrasing in the question directly matches this standard nomenclature, making this the accurate answer.

Option C: butter
- Butter is a food product that contains triglycerides, but it is not the chemical name of the lipid itself. Selecting this option would confuse a product with the molecular structure. While butter is rich in triglycerides, the diagram represents the lipid class, not a specific food item. Therefore this choice is semantically incorrect.

Option D: tres leches
- Tres leches is a type of dessert cake soaked in three milks. It has no scientific meaning in lipid chemistry and is unrelated to the molecular structure described. This is a distractor that relies on a pun or misdirection rather than chemical accuracy, so it is incorrect.

Summary: The question asks for the chemical name of a molecule with a glycerol backbone and three fatty acids, which is textbook-defined as a triglyceride. The first option mislabels the fatty acid composition, the second option correctly names the molecule, and the last two options refer to food items rather than molecular structure. The correct choice is triglyceride.
