Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.010\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] N#C/C(=C\c1ccccc1)C(=O)Nc1nncs1
[b] C=CCn1c(SCc2cc(C(=O)OC)c(C)o2)nnc1-c1ccncc1
[c] CCOC(=O)COc1nc(-c2ccc(Cl)cc2)cc(-c2ccco2)c1C#N
Answer: c. CCOC(=O)COc1nc(-c2ccc(Cl)cc2)cc(-c2ccco2)c1C#N
