Task: Answer the multiple choice question.
Query: Which compound has a 18.413\% 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 Cc1[nH]n(-c2ccccc2)c(=O)c1N=Nc1cccc(S(=O)(=O)N2CCOCC2)c1
b COC(=O)CC1(Cc2ccccc2)C(=O)NC(=O)NC1=O
c Cc1ccc(S(=O)(=O)Nc2ccccc2C(N)=O)c([N+](=O)[O-])c1
Answer: b. COC(=O)CC1(Cc2ccccc2)C(=O)NC(=O)NC1=O
