Task: Answer the multiple choice question.
Query: Which compound exhibits a 4.465\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. CCC(=O)Nc1ccc(S(=O)(=O)Nc2c(C)nc3nc[nH]n3c2=O)cc1
b. CCOC(=O)N1CCC(NC(=O)c2cc3c(-c4cccc(OC)c4)nn(C)c3s2)CC1
c. C=CCn1c(N2CCCCCC2)nc2c1c(=O)n(C)c(=O)n2C
Answer: c. C=CCn1c(N2CCCCCC2)nc2c1c(=O)n(C)c(=O)n2C
