Problem statement: Answer the multiple choice question.
Question: Which drug has a 5.556\% 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) CCOc1ccc(CN(C)CC(=O)NNC(=O)c2ccc(Cl)cc2)cc1OC
(b) O=c1[nH]c(=S)[nH]c2scc(-c3ccc(Br)cc3)c12
(c) CCC(=O)NC(c1cccs1)c1cc([N+](=O)[O-])c2cccnc2c1O
(d) CC(OC(=O)CNS(=O)(=O)c1ccc(C#N)cc1)C(=O)Nc1ccc(Cl)cn1
(e) COc1cc(/C(C)=N/NC(=O)CSc2nnc(C)s2)ccc1O
Answer: c. CCC(=O)NC(c1cccs1)c1cc([N+](=O)[O-])c2cccnc2c1O
