Task: Answer the multiple choice question.
Query: Which drug has a 12.942\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCN(C(=O)Cc1c(C(=O)O)n(CC)c2ccccc12)c1ccccc1C
(b) C=CCN1C(=O)C2(C(C#N)=C(N)Oc3n[nH]c(CCC)c32)c2ccccc21
Answer: b. C=CCN1C(=O)C2(C(C#N)=C(N)Oc3n[nH]c(CCC)c32)c2ccccc21
