Task: Answer the multiple-choice question.
Question: Which drug exhibits a -4.027\% 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(CS(=O)(=O)c1ccc(F)cc1)N1CCOCC1
[b] CCCCn1c(O)c(C(CC)=Nc2ccc(OCC)cc2)c(=O)[nH]c1=O
Answer: b. CCCCn1c(O)c(C(CC)=Nc2ccc(OCC)cc2)c(=O)[nH]c1=O
