Task: Answer the MCQ question.
Question: Which drug exhibits a -2.761\% 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 O=C(COC(=O)c1ccc(O)cc1)Nc1cc(S(=O)(=O)N2CCOCC2)ccc1Cl
b COc1ccc(Cn2cccc(NC(=O)Nc3cccc(C#N)c3)c2=O)cc1
c C=CCOc1c(Br)cc(/C=N/Nc2ccc(C(=O)O)cc2)cc1OCC
Answer: c. C=CCOc1c(Br)cc(/C=N/Nc2ccc(C(=O)O)cc2)cc1OCC
