Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.950\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=C(CN1C(=O)C2C3CC(C(Br)C3Br)C2C1=O)OCC(=O)c1cccc([N+](=O)[O-])c1
b: Cn1c(SCC(=O)N2CCc3ccccc32)nnc1C1CC1
c: O=C(NCc1ccccc1)NC1(C(=O)N2CCCC2)CCCCC1
Answer: a. O=C(CN1C(=O)C2C3CC(C(Br)C3Br)C2C1=O)OCC(=O)c1cccc([N+](=O)[O-])c1
