Task: Answer the multiple-choice question.
Question: Which drug has a 3.302\% 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] COc1ccc(NS(=O)(=O)c2cccc(NC(=O)c3cnccn3)c2)cc1Br
[b] O=C(/C=C/c1ccc(S(=O)(=O)NCc2ccco2)cc1)NCc1ccccc1Cl
[c] O=C(O)CCN1/C(=C/C=Nc2ccccc2)Oc2ccccc21
Answer: b. O=C(/C=C/c1ccc(S(=O)(=O)NCc2ccco2)cc1)NCc1ccccc1Cl
