Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.191\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CCCn1c(C)cc(C(=O)CN2C(=O)c3cccc(N)c3C2=O)c1C
[b] Cc1nn(CC#N)c(=O)n1-c1ccccc1F
[c] O=C(CCCc1ccccc1)NCc1cccnc1
Answer: b. Cc1nn(CC#N)c(=O)n1-c1ccccc1F
