Option 1 states that both lava and magma have gas. Lava refers to the molten rock that flows during a volcanic eruption, while magma is the molten rock beneath the Earth`s surface. Both lava and magma can contain dissolved gases, such as water vapor, carbon dioxide, sulfur dioxide, and others. These gases are released as pressure decreases during volcanic eruptions. Therefore, option 1 is correct.

Option 2 states that neither lava nor magma has gas. However, this statement is incorrect, as both lava and magma can contain gas.

Option 3 states that magma has gas while lava has no gas. This statement is incorrect because when magma reaches the Earth`s surface and becomes lava, it can still contain gases.

Option 4 states that lava has gas while magma has no gas. This statement is incorrect because when magma is beneath the Earth`s surface, it can contain dissolved gases.

In conclusion, option 1 is the correct statement.
