Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.184\% 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 additional words.
Options:
a: COc1ccc(OCc2nc3ccc(S(=O)(=O)Nc4ccccc4Cl)cc3[nH]2)cc1
b: C/C(=N/NC(=O)c1cn(-c2cccc(C)n2)cn1)c1ccc(C)cc1
c: CC1(C)CC(=O)c2c(S(C)(=O)=O)sc(Br)c2C1
d: CCOC(=O)C1CCN(C(=O)c2ccc(OCC(=O)N3CCOCC3)c(OC)c2)CC1
Answer: b. C/C(=N/NC(=O)c1cn(-c2cccc(C)n2)cn1)c1ccc(C)cc1
