Task: Answer the multiple choice question.
Query: Which compound has a -15.342\% 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 C=CCNCCOc1ccc(C)cc1[N+](=O)[O-].O=C(O)C(=O)O
b CCOC(=O)c1sc2nc(C)cc(-c3ccccc3)c2c1N
c COc1ccc([N+](=O)[O-])cc1NC(=O)CSc1nccc(C)n1
d COc1ccc(C(=O)N2CCN(c3c(C)cccc3C)CC2)cc1OC
Answer: d. COc1ccc(C(=O)N2CCN(c3c(C)cccc3C)CC2)cc1OC
