Problem statement: Answer the multiple choice question.
Question: Which drug has a -1.365\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=S1(=O)CCN(Cc2ccccn2)CC1
b. COc1ccc(S(=O)(=O)Nc2cc3c4c(oc3c3ccccc23)CC(C)(C)CC4=O)cc1
c. CC1CCN(c2nc(N(C)c3ccccc3)nc(N)c2[N+](=O)[O-])CC1
Answer: a. O=S1(=O)CCN(Cc2ccccn2)CC1
