Task: Answer the multiple-choice question.
Query: Which compound exhibits a 11.149\% 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 O=C(c1ccc(Cl)c(S(=O)(=O)N2CCOCC2)c1)N1CCCCC1
b Cc1ccc(-n2nc3c(=O)n(C(C)C(=O)NC4CC4)nc(C)c3c2C)cc1
c COc1ccc(-n2nc3c(c2NC(=O)c2ccc(Br)o2)CS(=O)(=O)C3)cc1
d O=[N+]([O-])c1ccc(S(=O)(=O)NNc2ncccc2[N+](=O)[O-])cc1
Answer: a. O=C(c1ccc(Cl)c(S(=O)(=O)N2CCOCC2)c1)N1CCCCC1
