Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.975% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COC(=O)c1cnn(C(=O)c2ccccc2Br)c1N
b: COc1ccc(/C=C/c2ccncc2)cc1
c: CC(C)c1ccc(/C=C2\SC(=S)N(CCC(=O)N3CCCCC3CCO)C2=O)cc1
Answer: b. COc1ccc(/C=C/c2ccncc2)cc1
