Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a -8.165\% 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, c, or d without using any other words.
Options:
a: Nc1c2nc(-c3ccccc3Cl)[nH]c(=O)c2nc(=O)n1-c1ccccc1
b: COC(=O)CCC(=O)OC1(C)C(=O)C=C2C=C(C3CC3)N(Cc3ccco3)C=C2C1=O
c: COc1ccc(-c2nn(-c3ccccc3)cc2C(=O)Nc2nc(CC(C)=O)ns2)cc1
d: O=C(Nc1ccc(S(=O)(=O)Nc2cnc3ccccc3n2)cc1)c1ccc(Br)o1
Answer: d. O=C(Nc1ccc(S(=O)(=O)Nc2cnc3ccccc3n2)cc1)c1ccc(Br)o1
