Task: Answer the multiple choice question.
Question: Which drug has a -9.493% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: COc1ccc(S(=O)(=O)Oc2cccc(/C=N/N=C3/NC(=O)C(CC(=O)O)S3)c2)cc1
b: CCc1ccccc1NC(=S)/N=C(\N)Nc1nc(C)c2cc(C)ccc2n1
c: CCN(CCO)Cc1cc(=O)oc2c(C)c(C)ccc12
Answer: b. CCc1ccccc1NC(=S)/N=C(\N)Nc1nc(C)c2cc(C)ccc2n1
