Task: Answer the multiple choice question.
Question: Which compound exhibits a -1.983\% 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: COc1cc(C2C(C#N)=C(N)N(c3cccnc3)C3=C2C(=O)CCC3)ccc1O
b: CCCOc1ccc(C(=O)Nc2c[nH]c(=O)[nH]c2=O)cc1
Answer: b. CCCOc1ccc(C(=O)Nc2c[nH]c(=O)[nH]c2=O)cc1
