Task: Answer the multiple-choice question.
Question: Which compound exhibits a 4.808\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=c1c2ccc([N+](=O)[O-])cc2ncn1CCOc1ccccc1
b: Cc1c(NS(=O)(=O)c2ccc(N(C)C3CCCCC3)c([N+](=O)[O-])c2)c(=O)n(-c2ccccc2)n1C
c: COc1ccc(OCc2cc(C(=O)N3CCCC(O)C3)no2)c2ccccc12
d: CC(Oc1ccc2ccc(=O)oc2c1)C(=O)NC1CC(C)(C)NC(C)(C)C1
Answer: a. O=c1c2ccc([N+](=O)[O-])cc2ncn1CCOc1ccccc1
