Task: Answer the multiple choice question.
Question: Which compound has a 3.252\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] CCCCn1c(N)c(N(CC(C)C)C(=O)Cn2c(=O)cnc3ccccc32)c(=O)[nH]c1=O
[b] COc1ccccc1CNC(=O)c1cc(=O)c2ccccc2o1
[c] O=C(O)Cn1nc2ccccc2n1
[d] CC1=NN(C(C#N)c2ccccc2)C(C)(C)C1
Answer: d. CC1=NN(C(C#N)c2ccccc2)C(C)(C)C1
