Task: Answer the multiple-choice question.
Query: Which drug exhibits a 32.237\% hERG inhibition at 1uM?
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(NCc1ccc(F)cc1F)Nc1cnccc1C(F)(F)F
b. COc1cc(/C=N\NC(=O)CNC(=O)C(c2ccccc2)c2ccccc2)ccc1O
c. CC1COC2N=C(N[N+](=O)[O-])NC2O1
d. COc1ccc(/C=C/C(=O)NCc2ccccn2)cc1OC
e. COc1ccc(NC(=S)Nc2ccc(N)c([N+](=O)[O-])c2)cc1
Answer: c. CC1COC2N=C(N[N+](=O)[O-])NC2O1
