Problem statement: Answer the multiple-choice question.
Query: Which drug has a 18.067\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1cc(/C=N/NC(=O)c2nonc2C)ccc1O
[b] CCOP(=O)(Cc1cc(C#N)oc1C)OCC
[c] O=C(OCc1ccccc1Cl)C1CC(=O)N(Cc2ccco2)C1
Answer: a. COc1cc(/C=N/NC(=O)c2nonc2C)ccc1O
