Both answer choices C and D could be supported by the information in the table. The table shows that methane (CH4) and propane (C3H8) are two different compounds with different properties, such as boiling point and gas density. This suggests that two elements (carbon and hydrogen) can combine to produce different substances (methane and propane) with different properties. This supports conclusion C. Additionally, the table does not provide any information about mixing compounds together, so there is no direct evidence to support conclusion D. Therefore, conclusion C is the best supported by the information in the table.
