Problem statement: Answer the multiple-choice question.
Question: Which drug has a -2.156\% 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=S(=O)(Nc1nccs1)c1ccc(Cl)cc1
b.) Cc1ccc2nc(N(CCCN(C)C)C(=O)c3ccc(S(=O)(=O)N4CCc5ccccc5C4)cc3)sc2c1.Cl
c.) C=CCNc1nnc(SCC(=O)Nc2ccccc2OC)c2ccccc12
Answer: a. O=S(=O)(Nc1nccs1)c1ccc(Cl)cc1
