Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.691\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CCc1nn(-c2cc(Oc3cccc4ccccc34)nc(-c3ccccc3)n2)c(N)c1C#N
b: CC(C)N1C(=O)C2C(C(=O)NC3CCCCC3)C3C=CC2(O3)C1C(=O)NC1CCCCC1
Answer: b. CC(C)N1C(=O)C2C(C(=O)NC3CCCCC3)C3C=CC2(O3)C1C(=O)NC1CCCCC1
