Task: Answer the multiple choice question.
Question: Which drug exhibits a -2.753\% 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: Nc1ncccc1OCc1ccc(Cl)c(Cl)c1
b: Nn1c(Cc2ccccc2F)nnc1SCCOc1ccc(Cl)cc1
c: O=C(Nc1cccc(-n2cnnn2)c1)c1ccoc1COc1ccc(Cl)cc1
Answer: b. Nn1c(Cc2ccccc2F)nnc1SCCOc1ccc(Cl)cc1
