Task: Answer the multiple choice question.
Question: Which drug exhibits a 11.287\% human ether-à-go-go related gene (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) COc1ccc(C(C)=O)cc1COC(=O)c1ccc(OCc2c(C)noc2C)cc1
(b) C/C(=C\C(=O)c1ccc(C)cc1)Nc1cccc(O)c1
Answer: b. C/C(=C\C(=O)c1ccc(C)cc1)Nc1cccc(O)c1
