Task: Answer the multiple-choice question.
Question: Which compound has a 10.989\% 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 NS(=O)(=O)c1ccc(S(=O)(=O)N(CCc2ccccc2)Cc2ccccn2)cc1
b O=C(Cc1ccc(-n2c(=O)c3sccc3n(CC(=O)Nc3ccccc3F)c2=O)cc1)NCc1ccco1
c COc1ccc(OCC(=O)NNC(=S)NC(=O)c2ccc([N+](=O)[O-])cc2)cc1
d CC(=O)N1CCOc2ccc(S(=O)(=O)NCCc3ccc(Cl)cc3)cc21
Answer: a. NS(=O)(=O)c1ccc(S(=O)(=O)N(CCc2ccccc2)Cc2ccccn2)cc1
