Task: Answer the multiple-choice question.
Query: Which drug exhibits a 19.046\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COC(=O)C(NNc1ccccc1)(NC(=O)c1cccc(F)c1)C(F)(F)F
(b) Cc1ccc(N2C(=O)NC(=O)C(CCc3ccccn3)(Cc3ccc(F)cc3)C2=O)cc1
(c) O=c1[nH]nc(-c2ccc(NCCO)c([N+](=O)[O-])c2)c2ccccc12
(d) CCOC(=O)c1cccc(NC(=O)Nc2ccc3c(c2)C(=O)OC3)c1
Answer: c. O=c1[nH]nc(-c2ccc(NCCO)c([N+](=O)[O-])c2)c2ccccc12
