Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 10.417\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCCc1ccc(-c2cc(C(=O)NC3=NCCS3)c3ccccc3n2)cc1
b O=C(Cc1ccc([N+](=O)[O-])cc1)Nc1ccc(Cl)cc1
c O=c1nccc(NCc2ccco2)[nH]1
d O=S(=O)(c1ccc(-c2ccccc2)cc1)N1CCCCC1
e O=C(Oc1cc(=O)oc2ccccc12)c1cccnc1Cl
Answer: b. O=C(Cc1ccc([N+](=O)[O-])cc1)Nc1ccc(Cl)cc1
