Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.455\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CN(Cc1ccco1)S(=O)(=O)c1nnc(NC(=O)c2ccccc2Cl)s1
[b] CN(CC(=O)Nc1ccccc1Br)C(=O)c1ccc(-c2ccc(Cl)cc2)o1
[c] CC(Nc1cccc2ccccc12)C(=O)N/N=C/c1ccc([N+](=O)[O-])cc1
[d] N#C/C(=C\c1ccc(OC(=O)c2ccc(Br)s2)cc1)c1nc2ccccc2[nH]1
Answer: b. CN(CC(=O)Nc1ccccc1Br)C(=O)c1ccc(-c2ccc(Cl)cc2)o1
