Task: Answer the multiple choice question.
Query: Which compound exhibits a 22.351\% 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 additional words.
Options:
(a) COc1ccccc1CNC(=O)c1c(O)c2cc(OC)c(OC)cc2[nH]c1=O
(b) CCOc1cc(C2C(C(=O)N3CCCCC3)=C(C)NC3=C2C(=O)CC(C)(C)C3)ccc1O
(c) O=C(COc1ccccc1C(=O)NCC1CCCO1)Nc1ccc(Cl)cc1Cl
(d) O=C(c1cccc([N+](=O)[O-])c1)N1CC2C3C=CC(C3)C2C1
Answer: d. O=C(c1cccc([N+](=O)[O-])c1)N1CC2C3C=CC(C3)C2C1
