Task: Answer the multiple choice question.
Query: Which compound has a 5.253\% 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: C(=C/c1ccccc1)\C=N\Nc1nc2ccccc2[nH]1
b: O=c1[nH]c2ccccc2nc1Cc1ccc([N+](=O)[O-])cc1
c: CC(C)(C)c1ccc(C(=O)NCC(=O)NNC(=O)c2ccccc2O)cc1
Answer: b. O=c1[nH]c2ccccc2nc1Cc1ccc([N+](=O)[O-])cc1
