Starting from
[tex]x^2=12y[/tex]Displacing the graph 1 unit to the left, we'll have:
[tex]\begin{gathered} x^2=12y \\ \rightarrow(x+1)^2=12y \end{gathered}[/tex]Displacing the graph 2 units up, we'll have:
[tex]\begin{gathered} (x+1)^2=12y \\ \rightarrow(x+1)^2=12(y-2) \end{gathered}[/tex]Thereby, the correct answer is: Option C
