Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.571\% 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 other words.
Options:
a) Cc1ccc([N+](=O)[O-])cc1NC(=O)CCSc1ccc(Cl)cc1
b) CC(=O)Oc1cc(O)c2c(c1)OC(c1ccc(OC(C)=O)c(OC(C)=O)c1)C(OC(C)=O)C2=O
Answer: b. CC(=O)Oc1cc(O)c2c(c1)OC(c1ccc(OC(C)=O)c(OC(C)=O)c1)C(OC(C)=O)C2=O
