Answer

Answer:

C. It contains fewer volatile gases

Explanation:

Step1: Recall lava - silica relationship

Lava with low silica content has certain properties.

Step2: Understand volatile gas behavior

Low - silica mafic lava has lower viscosity and allows gases to escape more easily, so it has fewer volatile gases.
