Proportional relationships are relationships between two variables where their ratios are equivalent.
From the table given;
g:h are respectively;
[tex]\begin{gathered} 3\colon9=1\colon3 \\ 6\colon36=1\colon6 \\ 9\colon81=1\colon2 \end{gathered}[/tex]Since the ratios above are not equivalent, their relationship is not proportional.
Hence, the correct option is B
