Task: Answer the multiple choice question.
Question: Which drug exhibits a -8.162\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] C#CCOCCOCCOCCNc1nc(N2CCN(C(=O)[C@H](CCC(=O)O)n3cc(C(N)CC(C)C)nn3)CC2)nc(N2CCN(C(=O)[C@H](CCC(=O)O)n3cc(C(N)[C@H](C)CC)nn3)CC2)n1.Cl
[b] Fc1ccccc1Cc1nnc2n1N=C(c1ccc(Cl)cc1)CS2
Answer: b. Fc1ccccc1Cc1nnc2n1N=C(c1ccc(Cl)cc1)CS2
