Task: Answer the MCQ question.
Query: Which compound has a 13.889\% 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=c1[nH]c(/C=C/c2ccc(Cl)cc2Cl)c([N+](=O)[O-])c(=O)[nH]1
b: CCC(C)c1ccc(NC(=O)c2ccco2)cc1
c: CCCN(CCC)C(=O)c1cc(S(=O)(=O)N2CCCCC2)c[nH]1
d: COC(=O)c1ccc(NC(=O)CCC(=O)c2ccc(F)cc2)cc1
Answer: a. O=c1[nH]c(/C=C/c2ccc(Cl)cc2Cl)c([N+](=O)[O-])c(=O)[nH]1
