Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.650\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] Cc1occc1-c1nnc(SCC(=O)c2c(N)n(C3CC3)c(=O)[nH]c2=O)n1C
[b] O=C(O)C1=C[C@H](C2CC2)C[C@H](OCc2ccc(CO)cc2)O1
[c] COc1ccc(N2CC(O)=C(c3nc(-c4ccccc4)cs3)C2=N)cc1
[d] Nc1cc(=O)[nH]c(SCc2cccc(Cl)c2)n1
Answer: c. COc1ccc(N2CC(O)=C(c3nc(-c4ccccc4)cs3)C2=N)cc1
