Task: Answer the multiple choice question.
Question: Which drug has a 2.056\% 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] Cc1cc(C)c(S(=O)(=O)n2ccc3ccccc32)c(C)c1
[b] O=C1C(=O)N(CCN2CCCCC2)c2ccccc21
[c] CCC(C)(C)n1nnnc1C(c1ccc(O)c(OC)c1)N1CCc2ccccc2C1.Cl
Answer: b. O=C1C(=O)N(CCN2CCCCC2)c2ccccc21
