Task: Answer the multiple choice question.
Question: Which drug exhibits a -30.085\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: O=C(N/N=C/c1ccc(OC(=O)c2ccco2)cc1)c1ccccn1
b: CCOc1cc(/C=C2\N=C(SCC)SC2=O)cc([N+](=O)[O-])c1OC(C)=O
c: CCOC(=O)CC(=O)Nc1cc(Cl)ccc1O
d: Cc1ccc(NS(=O)(=O)c2cccc3cccnc23)c(Br)c1
e: COc1ccc(N2CCN(C(=O)c3ccc(Br)cc3)CC2)c([N+](=O)[O-])c1
Answer: e. COc1ccc(N2CCN(C(=O)c3ccc(Br)cc3)CC2)c([N+](=O)[O-])c1
