Answer: (A)

Verified step by step guidance

1. Understand the classification of lipids: Lipids are a diverse group of molecules that include triglycerides, phospholipids, steroids, and waxes. Each type has distinct structural and functional characteristics.
2. Recall the structure and function of steroids: Steroids are a type of lipid characterized by a core structure of four fused carbon rings. They often function as hormones, such as cortisol, testosterone, and estrogen.
3. Identify the role of cortisol: Cortisol is a hormone involved in stress response, metabolism regulation, and immune function. Its role as a hormone aligns with the characteristics of steroids.
4. Compare cortisol to other lipid types: Triglycerides are energy storage molecules, phospholipids are key components of cell membranes, and waxes provide protective coatings. None of these functions match cortisol's role as a hormone.
5. Conclude that cortisol is classified as a steroid: Based on its structure (four fused rings) and function (hormonal activity), cortisol fits the definition of a steroid lipid.
