D. The Supremacy clause
The answer is D. The Supremacy clause
Explanation:
In the lawsuit which involved a 12 year old girl prone to seizures and taking marijuana as medicine suing the Federal Government and the DEA, the defendants are the Federal Government and DEA and the only way they can win the case is by applying the Supremacy clause which states that Federal laws are superior to State laws.
Although some states have legalized the use of marijuana, the Federal Government still considers the use of marijuana as illegal.
