Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.662% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] CC1=CC(C)(C)N2C(=O)C3(C(C#N)=C(N)Oc4cc(C)oc(=O)c43)c3cc(C)cc1c32
[b] O=C(Nc1nccs1)[C@@H]1CC=C[C@@H]2CCN(Cc3ccccc3)C(=O)[C@@H]21
[c] O=C(Nc1ccnc(-c2ccncc2)n1)c1ccc(Cl)cc1
[d] CSc1nnc(N2C(=O)C(O)=C(C(=O)c3ccco3)C2c2ccccc2F)s1
[e] COc1cc(-c2nnc(-c3ccco3)o2)ccc1OCc1ccccc1
Answer: c. O=C(Nc1ccnc(-c2ccncc2)n1)c1ccc(Cl)cc1
