Task: Answer the multiple choice question.
Query: Which compound exhibits a -16.170% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(OCc1cccc([N+](=O)[O-])c1)c1cccnc1Cl
[b] CCCCn1c(=O)cc(O)c2ccccc21
[c] CC(=O)c1ccc(-n2c(C)c(C(C)=O)c3cc(O)ccc32)cc1
[d] O=C1c2oc3ccccc3c(=O)c2C(c2ccc(O)cc2)N1c1nccs1
[e] CCN(CC(=O)N1CCc2ccccc2C1)S(=O)(=O)c1ccc2ccccc2c1
Answer: a. O=C(OCc1cccc([N+](=O)[O-])c1)c1cccnc1Cl
