Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.952\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CC(C)CN(C(=O)CC(C)c1ccccc1)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
(b) CCOC(=O)C(=Nc1ccccc1)NO
(c) CCCN(CC(=O)Nc1ccc(C(C)=O)cc1)CC(=O)Nc1ccccc1C
Answer: b. CCOC(=O)C(=Nc1ccccc1)NO
