Task: Answer the MCQ question.
Question: Which drug exhibits a 10.869% 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] CCc1ccc(N/C(SCc2ccccc2C)=C(/C#N)C(=O)NCc2ccco2)cc1
[b] Cc1c(-c2ccco2)[n+](=O)c2c(n1[O-])CCCCC2
[c] CCn1c(SCC(=O)Nc2cc(C)on2)nnc1-c1ccc(OC)cc1
Answer: b. Cc1c(-c2ccco2)[n+](=O)c2c(n1[O-])CCCCC2
