Task: Answer the multiple-choice question.
Question: Which compound exhibits a -8.407\% 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) Cn1c(=O)c2cc(S(=O)(=O)NC(Cc3ccccc3)C(=O)NCc3ccco3)ccc2n(C)c1=O
b) O=C(CNC(=O)c1ccc(Br)cc1)NC1CC1
c) O=C(CCCCl)OCc1cn(-c2ccc(Cl)cc2)nn1
d) COc1ccc2c(c1)C1(Nc3ccccc3-c3nc4ccccc4n31)C(=O)N2C
Answer: a. Cn1c(=O)c2cc(S(=O)(=O)NC(Cc3ccccc3)C(=O)NCc3ccco3)ccc2n(C)c1=O
