Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 5.589\% 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#Cc1ccc2ccn(CC(=O)NCc3ccco3)c2c1
b O=C1CC(=O)N(Cc2cccs2)C(=O)N1
c CC(=O)N(C(C)=O)n1c(/C=C/c2ccc([N+](=O)[O-])cc2)nc2ccccc2c1=O
Answer: b. O=C1CC(=O)N(Cc2cccs2)C(=O)N1
