Task: Answer the multiple choice question.
Question: Which compound has a -7.253\% 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(COC(=O)c1ccc[nH]c1=O)NCCc1ccc(F)cc1
[b] CCOC(=O)C(=O)NCc1ccc(/C=C2\C(=O)C(C(=O)OC)=C(C)N2c2ccc(C)c(C)c2)o1
Answer: b. CCOC(=O)C(=O)NCc1ccc(/C=C2\C(=O)C(C(=O)OC)=C(C)N2c2ccc(C)c(C)c2)o1
