Task: Answer the multiple-choice question.
Question: Which drug exhibits a -13.896% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CCN(CC)S(=O)(=O)c1ccc(C(=O)NCC(=O)NC2CC2)cc1
(b) O=[N+]([O-])c1cc([N+](=O)[O-])c(Nc2cccnc2)c([N+](=O)[O-])c1
(c) COc1ccc(C(=O)NC2=Nc3ccccc3N=C(C)C2c2ccccc2)cc1
(d) Cc1ccc(NC(=O)N(C)c2ccccc2)cc1
Answer: b. O=[N+]([O-])c1cc([N+](=O)[O-])c(Nc2cccnc2)c([N+](=O)[O-])c1
