Task: Answer the multiple-choice question.
Query: Which drug has a 4.711% 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: CC(C(=O)N=Nc1c(O)n(C)c2ccc(Br)cc12)n1cnc2ccccc2c1=O
b: CCCC(=O)c1c(O)[nH]c(=O)[nH]c1=O
Answer: b. CCCC(=O)c1c(O)[nH]c(=O)[nH]c1=O
