Task: Answer the multiple-choice question.
Query: Which drug exhibits a -1.275\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COC(=O)C(C)n1cnc2c(cnn2-c2ccc(Cl)cc2)c1=O
[b] COc1ccc2[nH]c(C)c(CN3CCCCC3)c(=O)c2c1
[c] O=C(Nc1cc2c3c(c1)CC(=O)N3CCC2)c1ccc(Br)o1
Answer: c. O=C(Nc1cc2c3c(c1)CC(=O)N3CCC2)c1ccc(Br)o1
