Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a 13.922\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] O=C(Nc1ccc2c(c1)OCO2)C1CCCCN1S(=O)(=O)c1ccccc1
[b] COC(=O)CNC(c1ccccc1)c1cc(C)ccc1NC(=O)c1cccc(Cl)c1
[c] CCC(=O)Nc1ccc(/C(C)=N/NC(=O)c2c(-c3ccccc3Cl)noc2C)cc1
[d] CC1(c2nnc(-c3cccc(Cl)c3)o2)CC(c2ccc([N+](=O)[O-])cc2)=NO1
Answer: d. CC1(c2nnc(-c3cccc(Cl)c3)o2)CC(c2ccc([N+](=O)[O-])cc2)=NO1
