Biology

The correct answer is: A.C, H, O.

Here's why:

Lipids are primarily composed of carbon (C), hydrogen (H), and oxygen (O). They typically have long hydrocarbon chains (made of carbon and hydrogen) and may contain some oxygen, but they generally lack significant amounts of nitrogen, phosphorus, or sulfur.

For further clarification:

A.C, H, O: This is the typical composition of most lipids, including fats, oils, and phospholipids. They contain a backbone of carbon and hydrogen atoms, with oxygen present in functional groups like carboxyl groups (as in fatty acids) or ester linkages (as in triglycerides).
