(D) We have $\int_{-2}^2 |[x]| \, dx = \int_{-2}^{-1} |[x]| \, dx + \int_{-1}^0 |[x]| \, dx + \int_0^1 |[x]| \, dx + \int_1^2 |[x]| \, dx$. Since $[x]$ is the greatest integer function: For $x \in [-2, -1)$,$[x] = -2$,so $|[x]| = |-2| = 2$. For $x \in [-1, 0)$,$[x] = -1$,so $|[x]| = |-1| = 1$. For $x \in [0, 1)$,$[x] = 0$,so $|[x]| = |0| = 0$. For $x \in [1, 2)$,$[x] = 1$,so $|[x]| = |1| = 1$. Substituting these values: $\int_{-2}^2 |[x]| \, dx = \int_{-2}^{-1} 2 \, dx + \int_{-1}^0 1 \, dx + \int_0^1 0 \, dx + \int_1^2 1 \, dx$. $= 2[x]_{-2}^{-1} + [x]_{-1}^0 + 0 + [x]_1^2$. $= 2(-1 - (-2)) + (0 - (-1)) + (2 - 1)$. $= 2(1) + 1 + 1 = 4$.

$\int_{-2}^2 |[x]| \, dx$ is equal to
