B Correct answer
Explanation

Tetrafluoromethane (CF4) is a gas at room temperature and ordinary pressure due to its low boiling point. Carbon tetrachloride (CCl4) is a liquid, and carbon tetrabromide (CBr4) is a solid at room temperature. Cl4 is not a standard stable chemical formula for a simple molecule like the others listed.
