Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.400\% 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. O=C(Nc1cccc(-n2cnnn2)c1)c1ccc(C(F)(F)F)cc1
b. O=c1n(-c2ccccc2)c(=O)n2n1CCC2
Answer: b. O=c1n(-c2ccccc2)c(=O)n2n1CCC2
