Task: Answer the multiple-choice question.
Query: Which compound exhibits a -0.726\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(CCc1ccc(O)cc1)N/N=C/c1coc2ccccc2c1=O
(b) O=C(CNC1CCCCC1)Nc1cc(S(=O)(=O)N2CCOCC2)ccc1Cl
(c) O=C(CNc1c(Br)cc(Br)cc1Br)NN=C1CCCCC1
Answer: c. O=C(CNc1c(Br)cc(Br)cc1Br)NN=C1CCCCC1
