Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.379% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: C=CCn1c(O)c(C(C)=NCc2ccc3c(c2)OCO3)c(=O)[nH]c1=O
b: COc1ccc(-c2nc(-c3ccncc3)no2)c(OC)c1
Answer: b. COc1ccc(-c2nc(-c3ccncc3)no2)c(OC)c1
