Problem statement: Answer the multiple-choice question.
Query: Which drug has a -1.329\% 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: N/C(=N\c1nc2ccccc2o1)NC(=O)c1ccc([N+](=O)[O-])cc1
b: Cc1nn(C)c(Cl)c1/C=N/OC(=O)c1ccccc1
c: Cl.NC(=NCc1ccccc1)c1cccc([N+](=O)[O-])c1
Answer: a. N/C(=N\c1nc2ccccc2o1)NC(=O)c1ccc([N+](=O)[O-])cc1
