Task: Answer the multiple choice question.
Question: Which drug exhibits a -5.367\% 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 additional words.
Options:
a COc1ccc(-n2cc3ccc([N+](=O)[O-])cc3n2)cc1
b C=CCC1(CC=C)CCCN1C(=O)C1CCC(=O)N(CCc2ccccc2)C1
c O=C(Nc1ccccc1)OC1CN=C(N[N+](=O)[O-])NC1
Answer: c. O=C(Nc1ccccc1)OC1CN=C(N[N+](=O)[O-])NC1
