Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a -0.275\% 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] COc1cccc(OC)c1OCCN(C)C.O=C(O)C(=O)O
[b] O=C(OCC(=O)N1CCc2ccccc21)c1ccc([N+](=O)[O-])cc1
[c] O=Cc1ccc(OCc2nnc(-c3ccccc3Br)o2)cc1
[d] Cc1ccc(C(=O)NCC(=O)NCCCc2ccccc2)s1
Answer: c. O=Cc1ccc(OCc2nnc(-c3ccccc3Br)o2)cc1
