Task: Answer the multiple choice question.
Question: Which drug exhibits a -1.638\% 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. Cn1cnnc1SCC(=O)Nc1ccc(Br)cc1F
b. O=C(NCCc1ccco1)c1cc(COc2cccc(C(F)(F)F)c2)on1
c. CN(C)C(=O)CN(C)S(=O)(=O)c1ccc(Cl)cc1
Answer: c. CN(C)C(=O)CN(C)S(=O)(=O)c1ccc(Cl)cc1
