Task: Answer the multiple choice question.
Question: Which drug exhibits a -0.505\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CC(C)(C)C(=O)NC(NC(=S)Nc1ccc(S(N)(=O)=O)cc1)C(Cl)(Cl)Cl
b: COc1cc2c(cc1OC)-c1cc(NC3CCCCC3)nc(=O)n1CC2
c: CCN(C1CCS(=O)(=O)C1)S(=O)(=O)c1ccc(OC)c(OC)c1
d: CC(Oc1ccccc1)C(=O)N=C1SC2CS(=O)(=O)CC2N1c1ccc(F)cc1
e: NC(=O)CC(NC(=O)c1ccccc1)c1ccc(NCc2ccc(F)cc2)c([N+](=O)[O-])c1
Answer: b. COc1cc2c(cc1OC)-c1cc(NC3CCCCC3)nc(=O)n1CC2
