Task: Answer the multiple choice question.
Question: Which compound has a 0.708\% 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. N=C1S/C(=C\c2ccc(-c3cccc(Cl)c3)o2)C(=O)N1c1nccs1
b. O=C(O)CC(NC(=O)c1ccco1)c1ccco1
c. CN=Cc1c(NC)nc2c(C)cccn2c1=O
d. CC1=CC(C)(C)N(C(=O)CSc2nnc(-c3ccccc3)o2)c2ccc(C)cc21
Answer: c. CN=Cc1c(NC)nc2c(C)cccn2c1=O
