Task: Answer the multiple-choice question.
Question: Which drug exhibits a 12.085\% 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=[N+]([O-])c1ccc(Sc2nc3ccccc3o2)c([N+](=O)[O-])c1
b) O=C(N1CCOCC1)N1CCN(S(=O)(=O)N2CCCCC2)CC1
c) CC(C)(C)NC(=O)NC(=O)CSc1nnc(COc2ccccc2Cl)o1
Answer: a. O=[N+]([O-])c1ccc(Sc2nc3ccccc3o2)c([N+](=O)[O-])c1
