D) bones.

Answer

Answer: Phospholipids are an important structural component of the brain.

Explanation

Phospholipids are a class of lipids that are a major component of all cell membranes, forming bilayers that provide structural integrity and compartmentalization. In the brain, phospholipids are crucial for forming the myelin sheath that insulates neurons, ensuring efficient transmission of nerve impulses. Additionally, they play a role in signaling pathways and the overall health of neuronal cells. While phospholipids are also present in other tissues such as the liver, muscles, and bones, their distinctive role and concentration in the brain highlight their importance as a structural component specifically in that organ.
