Task: Answer the MCQ question.
Query: Which drug exhibits a -2.671\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: Br.C=CCN1CCc2cc(O)c(O)cc2C(c2ccccc2)C1
b: CCc1ccc(OCC(=O)Nc2ccc(-c3nc4ccccc4o3)c(O)c2)cc1
c: CCS(=O)(=O)NCc1nnc2n1-c1ccc(Br)cc1C(c1ccccc1Cl)=NC2
Answer: c. CCS(=O)(=O)NCc1nnc2n1-c1ccc(Br)cc1C(c1ccccc1Cl)=NC2
