Task: Answer the multiple choice question.
Question: Which compound exhibits a -47.238% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a COCCN1CC(=O)N(c2cccc(C)c2C)C(c2ccc(Cl)cc2)C1=O
b CCOC(=O)C1=C(CSc2nc(-c3ccncc3)ccc2C#N)OC(N)=C(C#N)C1c1cccnc1
c CCc1nnc(NC(=O)CSc2nnc(-c3ccccc3O)n2-c2ccc(C)cc2C)s1
d COc1ccccc1/C=C/C(=O)c1ccc(Cl)cc1
e Cc1ccc(/C=C/C(=O)Nc2ccc(S(=O)(=O)Nc3ncccn3)cc2)cc1
Answer: b. CCOC(=O)C1=C(CSc2nc(-c3ccncc3)ccc2C#N)OC(N)=C(C#N)C1c1cccnc1
