C.Assertion is a correct but Reason is incorrect
D.Both Assertion and Reason are incorrect

Answer 1

Hint: Mitochondrion, a membrane-bound organelle present in virtually all eukaryotic cells' cytoplasm, whose primary role is to produce large amounts of adenosine triphosphate (ATP) energy.

Complete answer:
First we should know about mitochondria to answer this question. Typically, mitochondria are circular to oval in form and range from 0.5 to 10 μm in scale. Mitochondria stores calcium for cell signalling activities, produces heat, and activates cell growth and mortality in addition to creating energy. The number of mitochondria per cell varies hugely; erythrocytes may not contain mitochondria in humans, for instance, while muscle and liver cells may comprise hundreds or even thousands of mitochondria.
Now, let us find the solution from the options-
- With the outer membrane and the inner membrane, every mitochondrion is a double membrane-bound system that divides the lumen separately into two aqueous compartments, i.e. the external compartment and the internal compartment.
- The matrix is contained in the inner compartment.
-The outer membrane forms the organelle's continual restrictive boundary.
-A set of folders called the cristae against the matrix are formed by the inner membrane. The cristae lifts the region of the surface.

Hence, the correct answer is option (C)

Note: The outer mitochondrial membrane comprises special channels capable of carrying large molecules, and is freely permeable towards small molecules. The inner membrane, by comparison, is much less permeable, allowing only very tiny molecules to pass through the gel-like matrix that makes up the core mass of the organelle.
