Task: Answer the multiple choice question.
Question: Which drug has a 18.523% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] CCOC(=O)C1=C(CN2CCN(C(=O)c3ccco3)CC2)NC(=O)NC1c1ccccc1
[b] O=C(O)c1ccc(-n2c(-c3cc(C4CC4)[nH]n3)n[nH]c2=S)cc1
Answer: b. O=C(O)c1ccc(-n2c(-c3cc(C4CC4)[nH]n3)n[nH]c2=S)cc1
