• A. Organic molecules are typically composed of metals and nonmetals.
• B. Organic molecules are always $\mathrm{ionic}$ compounds.
• C. Organic molecules primarily consist of $\mathrm{carbon}$ and $\mathrm{hydrogen}$ atoms.
• D. Organic molecules cannot contain $\mathrm{oxygen}$ atoms.

Answer: (C)

Verified step by step guidance

1. Identify the key elements that are typically found in organic molecules. Organic chemistry primarily deals with compounds containing carbon atoms.
2. Recognize that hydrogen is another common element in organic molecules, often forming hydrocarbons with carbon.
3. Understand that organic molecules can also contain other elements such as oxygen, nitrogen, sulfur, and halogens, but the backbone is primarily carbon and hydrogen.
4. Evaluate the given statements: Organic molecules are not typically composed of metals and nonmetals, nor are they always ionic compounds.
5. Conclude that the correct statement is that organic molecules primarily consist of carbon and hydrogen atoms, acknowledging that they can also include other elements like oxygen.
