Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 19.564\% 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=S(=O)(c1cc(Cl)c(Cl)cc1Cl)N1CCN2CCCC2C1
[b] CCn1c(CN2CCOCC2)nnc1SCC(=O)Nc1ccccc1Cl
[c] NC1=NC(=O)/C(=C/c2ccccc2OS(=O)(=O)c2ccc3ccccc3c2)S1
Answer: a. O=S(=O)(c1cc(Cl)c(Cl)cc1Cl)N1CCN2CCCC2C1
