Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 7.982\% 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] COc1cccc(C2NC(=O)CCC2[N+](=O)[O-])c1
[b] O=C1CCCC(O)=C1Sc1ccccc1C(=O)O
Answer: b. O=C1CCCC(O)=C1Sc1ccccc1C(=O)O
