Task: Answer the multiple choice question.
Question: Which compound has a -18.333\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: CCOc1ccc(NC(=O)CN(C)C(=O)c2ccc(NC3CC3)c([N+](=O)[O-])c2)cc1OCC
b: CCn1c2ccccc2c2nnc(SCC(=O)N(C)C3CCS(=O)(=O)C3)nc21
c: C=C1SC(=Nc2ccccc2Cl)N(C(=O)c2sc3ccccc3c2Cl)C1(C)C
d: O=C1CCCN2N=C(SCC(=O)Nc3ccc(Br)cc3)SC2=N1
e: OC(c1ccccc1)(c1ccc(Cl)cc1)C1CN2CCC1CC2
Answer: a. CCOc1ccc(NC(=O)CN(C)C(=O)c2ccc(NC3CC3)c([N+](=O)[O-])c2)cc1OCC
