Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -8.057\% 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) COc1cc(C2Nc3cc(C)c(C)cc3NC3=C2C(=O)CC(C)(C)C3)ccc1OC(C)=O
(b) CCCCOC(=O)C1=C(C)Nc2ncnn2C1c1ccc(OC)c(OC)c1OC
Answer: b. CCCCOC(=O)C1=C(C)Nc2ncnn2C1c1ccc(OC)c(OC)c1OC
