Task: Answer the multiple-choice question.
Query: Which compound has a -3.040\% 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 other words.
Options:
(a) O=C1C2C3C=CC(C3)C2C(=O)N1CCCO
(b) CCC(=O)Nc1ccc(C(=O)CN2C(=O)NC3(CCCCCC3)C2=O)cc1
(c) NC(=O)CC(NC(=O)c1ccccc1)c1ccc(NCCc2ccc(Cl)cc2)c([N+](=O)[O-])c1
(d) O=C(CCc1ccccc1)N1CCCC1
(e) COc1ccc(OCc2cc(C(=O)N3CCC(OC)CC3)no2)c2ccccc12
Answer: a. O=C1C2C3C=CC(C3)C2C(=O)N1CCCO
