Task: Answer the MCQ question.
Question: Which drug has a 3.818% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(COC(=O)C1CCC(=O)N1)Nc1cc(Cl)ccc1Cl
b: O=C(COC(=O)COc1ccccc1[N+](=O)[O-])Nc1ccccc1Br
c: CCCCCCCCCCCC(=O)NC(Cc1ccc(OC)c([N+](=O)[O-])c1)C(=O)[O-].[NH4+]
d: COc1ccc(/C=N/NC(=O)CNc2n[nH]c(=O)[nH]c2=O)cc1OC
Answer: b. O=C(COC(=O)COc1ccccc1[N+](=O)[O-])Nc1ccccc1Br
