Correct Answer

Explanation

The gas that can be dried using concentrated tetraoxosulphate (VI) acid (also known as sulfuric acid, H2SO4) is ammonia (NH3). Concentrated sulfuric acid is commonly used as a drying agent for gases because it can react with and remove water vapor, leaving the desired gas dry. This process is often used in laboratory settings or industrial applications to obtain dry and pure gases.
