Task: Answer the multiple choice question.
Question: Which drug has a 3.844\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COc1ccc(-c2ccc(C#N)c(SCC(=O)OCc3ccccc3)n2)cc1OC
b) O=C1C(c2ccccc2)=[N+]([O-])c2ccccc21
c) CCOC(=O)CNc1cccc(C(F)(F)F)c1
d) N#CC(C#N)=NNc1ccc([N+](=O)[O-])cc1
Answer: a. COc1ccc(-c2ccc(C#N)c(SCC(=O)OCc3ccccc3)n2)cc1OC
