Task: Answer the multiple choice question.
Question: Which drug has a 4.012\% 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 other words.
Options:
a: Cc1nn(C(C)(C)C)c(N)c1-c1ccccc1
b: CN1C=CC=C/C1=C(\C#N)c1nc2ccccc2[nH]1
Answer: b. CN1C=CC=C/C1=C(\C#N)c1nc2ccccc2[nH]1
