= Solution

For this <Heisenberg Lie algebra>,
$$
[\mathfrak g,\mathfrak g]=\mathbb Cc,
\qquad
[\mathfrak g,\mathbb Cc]=0,
$$
because $c$ belongs to the <Center of a Lie algebra>[center]. Thus its <Lower central series of a Lie algebra> is $\mathfrak g,\mathbb Cc,0$, so $\mathfrak g$ is a two-step <Nilpotent Lie algebra>.
