Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 6.600\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) CCN(CC)S(=O)(=O)c1ccc(NN)nc1
b.) CC(=O)O[C@]1(C(C)=O)CC[C@H]2[C@@H]3C=C(Cl)C4=CC(=O)CC[C@]4(C)[C@H]3CC[C@@]21C
Answer: a. CCN(CC)S(=O)(=O)c1ccc(NN)nc1
