Task: Answer the multiple choice question.
Query: Which compound exhibits a 8.463\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: COc1ccc(-c2nnsc2N2C(=O)c3ccccc3C2=O)cc1
b: O=C1CC(C(=O)NCc2ccccc2)C2(CCCC2)O1
c: CCCCN1Cc2c(nc3cc(-c4ccco4)[nH]n3c2=O)C1=O
d: O=C(CN1CCN(c2ccccn2)CC1)NC1CCCC1
Answer: c. CCCCN1Cc2c(nc3cc(-c4ccco4)[nH]n3c2=O)C1=O
