• A. Nitrogen
• B. Carbon
• C. Chlorine
• D. Sodium

Answer: (B)

Verified step by step guidance

1. Identify the chemical formulas given: carbon dioxide is \(\mathrm{CO_2}\) and glucose is \(\mathrm{C_6H_{12}O_6}\).
2. List the elements present in each compound: carbon dioxide contains carbon (C) and oxygen (O), while glucose contains carbon (C), hydrogen (H), and oxygen (O).
3. Compare the elements in both compounds to find the common ones: both contain carbon (C) and oxygen (O).
4. From the answer choices (Nitrogen, Carbon, Chlorine, Sodium), determine which element is present in both compounds. Carbon is present in both \(\mathrm{CO_2}\) and \(\mathrm{C_6H_{12}O_6}\).
5. Conclude that carbon is the key component found in both carbon dioxide and glucose.
