Task: Answer the multiple-choice question.
Question: Which compound exhibits a 13.588\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COc1cc(/C=N/NC(=O)C(=O)/C=C2\NC(C)(C)Cc3ccccc32)ccc1O
b: O=C1OC(c2ccc(F)cc2)=C/C1=C\c1ccc(O)cc1
Answer: b. O=C1OC(c2ccc(F)cc2)=C/C1=C\c1ccc(O)cc1
