Task: Answer the multiple-choice question.
Query: Which compound exhibits a 18.268\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] Cc1ccc(OCCCN2CCOCC2)c([N+](=O)[O-])c1.O=C(O)C(=O)O
[b] O=C(NC(=S)NCc1cccnc1)c1ccccc1F
[c] CCN1C(=O)c2cccc3cccc1c23
[d] C=CCOC(=O)C1=C[C@@H](c2ccc(C(F)(F)F)cc2)C[C@@H](OCc2ccc(CO)cc2)O1
Answer: d. C=CCOC(=O)C1=C[C@@H](c2ccc(C(F)(F)F)cc2)C[C@@H](OCc2ccc(CO)cc2)O1
