Task: Answer the multiple-choice question.
Question: Which drug exhibits a 1.319\% 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 COC(=O)CCC(=O)Nc1ccccc1C(N)=O
b Cc1cc(C)c2c3c(sc2n1)C(c1ccccc1)C(C#N)=C(N)O3
Answer: b. Cc1cc(C)c2c3c(sc2n1)C(c1ccccc1)C(C#N)=C(N)O3
