Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.554\% 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.) CN1C(=O)C(CCC(N)=O)NC1=S
b.) O=C(COC(=O)COc1cccc2ccccc12)NCC(F)(F)F
c.) O=C(CSc1nc2ccccc2c(=O)[nH]1)Nc1ccc(Br)cc1
d.) Nc1c(Cl)cc(C2=NCCn3nc4ccccc4c32)cc1Cl
Answer: b. O=C(COC(=O)COc1cccc2ccccc12)NCC(F)(F)F
