Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 8.027\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(O)CCCCCN1C(=O)CCC1=O
[b] O=C1C2CCCN2C(c2ccccc2F)N1c1ccc(Cl)cc1
Answer: b. O=C1C2CCCN2C(c2ccccc2F)N1c1ccc(Cl)cc1
