Step 1: Understand the context of the question. Living organisms are primarily composed of six fundamental elements, often referred to as CHNOPS: Carbon (C), Hydrogen (H), Nitrogen (N), Oxygen (O), Phosphorus (P), and Sulfur (S). These elements are essential for the structure and function of biomolecules.
Step 2: Review the options provided in the question: Sodium (Na), Carbon (C), Chlorine (Cl), and Iron (Fe). Compare each option to the six fundamental elements (CHNOPS).
Step 3: Eliminate the elements that are not part of CHNOPS. Sodium (Na), Chlorine (Cl), and Iron (Fe) are not among the six fundamental elements commonly found in living organisms.
Step 4: Identify Carbon (C) as one of the six fundamental elements. Carbon is a key component of organic molecules, such as carbohydrates, lipids, proteins, and nucleic acids, which are essential for life.
Step 5: Conclude that the correct answer is Carbon (C), as it is one of the six fundamental elements commonly found in living organisms.
