Task: Answer the multiple choice question.
Question: Which compound exhibits a 2.391\% human ether-à-go-go related gene (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(NC(=O)c2cc3ccccc3o2)cc1
b) COc1ccccc1N(CC(=O)N1CCCC1)S(C)(=O)=O
c) COc1cc(C(=O)Nc2sc3c(c2C(=O)O)CCC(C)C3)cc(OC)c1OC
Answer: b. COc1ccccc1N(CC(=O)N1CCCC1)S(C)(=O)=O
