Task: Answer the multiple-choice question.
Question: Which drug exhibits a -24.299% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CC(=O)c1ccc(NC(=O)CSc2nnc(Cc3cccn3C)n2-c2ccc(F)cc2)cc1
(b) CCN1c2cccc3cccc(c23)S1(=O)=O
(c) O=C(NCCS(=O)(=O)NCc1cccnc1)c1ccccc1
(d) Cl.N=c1ccn(Cc2cccc(Cl)c2)cc1
Answer: b. CCN1c2cccc3cccc(c23)S1(=O)=O
