D Correct answer
Explanation

Methylaluminoxane, is pyrophoric, and is violently reactive with any chemical bearing an acidic proton. However, it is generally used as a solution in an (aromatic) hydrocarbon due to its relatively high solubility in such hydrocarbons.It is most well known for being a co-catalyst for olefin polymerizations of the Ziegler-Natta type.
