Task: Answer the multiple choice question.
Query: Which compound has a -0.451\% 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) CC(=C1C2C=CC1C1C(=O)NC(=O)C21)c1ccccc1
(b) C=C(C)CSc1nc2c(c(=O)[nH]c(=O)n2C)n1CCC(C)C
(c) CCOC(=O)c1cc2c(C)nn(-c3ccccc3)c2s1
(d) COc1cc(/C=C2\SC(c3ccc(C)cc3)=NC2=O)ccc1O
(e) CCC(=O)NC(=S)Nc1ccc2oc(-c3ccc(OC)cc3)nc2c1
Answer: c. CCOC(=O)c1cc2c(C)nn(-c3ccccc3)c2s1
