Task: Answer the multiple-choice question.
Question: Which drug exhibits a 16.425\% 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 CCOC(=O)N1CCN(C(=O)c2c(Cl)cnn2C)CC1
b O=C(COC(=O)CSc1ccc([N+](=O)[O-])cc1)NCc1ccco1
c CC(C)N1C(=O)CCC1C(=O)N1CCN(c2ccccn2)CC1
Answer: b. O=C(COC(=O)CSc1ccc([N+](=O)[O-])cc1)NCc1ccco1
