Task: Answer the multiple-choice question.
Question: Which drug has a 0.261\% 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) COc1cc(OC)c(OC)cc1/C=C1\Oc2cc(OS(C)(=O)=O)ccc2C1=O
(b) COC(=O)c1cccc(NC(=O)Nc2ccccc2OC)c1
(c) COc1ccc(C2SCC(=O)N2CCc2ccc(OC)c(OC)c2)cc1
Answer: a. COc1cc(OC)c(OC)cc1/C=C1\Oc2cc(OS(C)(=O)=O)ccc2C1=O
