Task: Answer the multiple-choice question.
Query: Which drug exhibits a 23.952\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) O=C(O)c1cccc(Nc2ccc([N+](=O)[O-])cn2)c1
b) COc1cccc(CNc2ccc3[nH]c(=O)[nH]c3c2)c1OCc1ccccc1Cl
c) O=C(c1ccco1)N1CCN(c2c([N+](=O)[O-])nn(-c3cccc(Cl)c3)[n+]2[O-])CC1
Answer: b. COc1cccc(CNc2ccc3[nH]c(=O)[nH]c3c2)c1OCc1ccccc1Cl
