Task: Answer the multiple-choice question.
Query: Which drug exhibits a -0.400% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a. O=C1CCCCCN1C(=O)c1ccc(C(=O)N2CCCCCC2=O)cc1
b. COc1ccc(Cl)cc1NC(=O)Nn1cnnc1
c. O=C(NCC(O)c1ccc([N+](=O)[O-])cc1)c1cccc(S(=O)(=O)N2CCCC2)c1
Answer: b. COc1ccc(Cl)cc1NC(=O)Nn1cnnc1
