Task: Answer the multiple choice question.
Query: Which drug exhibits a -56.748\% 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) N/C(Cc1ccc([N+](=O)[O-])cc1)=N\OC(=O)c1ccc([N+](=O)[O-])cc1
b) COc1ccc(OC)c(-n2cnc3cc(C(=O)NCCCN4CCOCC4)ccc32)c1
c) O=C(CCCOc1ccccc1)NC1CCCc2ccccc21
Answer: a. N/C(Cc1ccc([N+](=O)[O-])cc1)=N\OC(=O)c1ccc([N+](=O)[O-])cc1
