Step 1: Understand the context of the question. The problem is asking about the primary elements that make up the cells in our bodies. This requires knowledge of the basic composition of living organisms.
Step 2: Recall that living organisms are primarily composed of elements that are essential for forming biomolecules such as proteins, carbohydrates, lipids, and nucleic acids. These biomolecules are the building blocks of cells.
Step 3: Identify the four most abundant elements in the human body. These are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N). These elements are involved in forming the backbone of organic molecules.
Step 4: Compare the options provided in the question. The correct answer is the option that lists carbon, hydrogen, oxygen, and nitrogen, as these are the primary elements found in cells.
Step 5: Conclude that the other options (e.g., zinc, copper, iodine, selenium; iron, magnesium, sodium, chlorine; calcium, phosphorus, potassium, sulfur) are trace elements or minerals that play specific roles but are not the primary elements making up the cells.
