Task: Answer the multiple-choice question.
Query: Which compound exhibits a 11.564\% 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: O=c1c2ccccc2nc(-c2ccccc2Cl)n1-c1ccc(O)cc1
b: Brc1ccc(CN2CCN(Cc3c[nH]c4ccccc34)CC2)cc1.O=C(O)C(=O)O
c: CCOC(=O)c1ccc(NC(=O)COc2ccccc2CNC2CCCC2)cc1.Cl
d: Cc1cc(C)n2nc(C(=O)N/N=C/c3ccco3)nc2n1
Answer: a. O=c1c2ccccc2nc(-c2ccccc2Cl)n1-c1ccc(O)cc1
