Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.027\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cn1c2ccccc2c2cnn(CC(=O)Nc3ccc(F)cc3F)c(=O)c21
b: O=C(c1cccc(F)c1)N1C2C=CC(C2)C1(C(F)(F)F)C(F)(F)F
Answer: a. Cn1c2ccccc2c2cnn(CC(=O)Nc3ccc(F)cc3F)c(=O)c21
