Solution

The correct option is A Concentrated sulphuric acid
Drying agents are substances capable of absorbing the moisture present in the substance. Sulphuric acid has a great affinity for water. It readily removes elements of water from other compounds i.e, it acts as a dehydrating agent, it being a hygroscopic substance absorb water from other substances without dissolving in it, so it is considered a drying agent.

So, the answer is concentrated sulphuric acid.
