Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 14.550\% 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: CCCCn1c(N)c(N(CCOC)C(=O)c2cc(-c3ccco3)nc3ccccc23)c(=O)[nH]c1=O
b: O=C(/C=C/c1cccs1)N1CCCCC1
c: OCCc1ccc(-c2ccc(Cl)cc2)o1
d: O=C(COC(=O)c1ccc([N+](=O)[O-])cc1Cl)Nc1cccnc1Cl
Answer: d. O=C(COC(=O)c1ccc([N+](=O)[O-])cc1Cl)Nc1cccnc1Cl
