Which one of the following is the double membrane-bound organelle?

Mitochondria is a double membrane-bound organelle found in eukaryotic cells. They have a unique structure consisting of an outer membrane and an inner membrane that folds inward to form cristae. The space between the two membranes is known as the intermembrane space, while the innermost compartment is called the matrix.

Single membrane-bound organelles in eukaryotic cells include lysosomes, Golgi apparatus, endoplasmic reticulum, and vacuoles.
