Task: Answer the multiple-choice question.
Query: Which drug exhibits a 18.009\% 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 other words.
Options:
[a] O=C(COC(=O)C12CC3CC(CC(Br)(C3)C1)C2)Nc1ccc2[nH]c(=O)[nH]c2c1
[b] Cc1cccc(C)c1OCc1nc2ccccc2c(=O)n1/N=C/c1ccc(OCC(=O)O)cc1
[c] O=C(O)c1ccc(NC(=O)C2COc3ccccc3O2)cc1
[d] CCOC(=O)C1=C(CSc2nc3ccccc3s2)NC(=O)NC1c1cc(C)ccc1C
Answer: c. O=C(O)c1ccc(NC(=O)C2COc3ccccc3O2)cc1
