Solution
The correct option is C Mitochondria
Each mitochondrion is surrounded by two membranes, outer and inner which are composed of lipoprotein. The outer membrane is smooth but inner membrane forms finger-like folds towards inner side. In animal cells, these folds are called cristae. The large central part enclosed by inner membrane is called inner chamber. It is filled with proteinaceous, homogeneous watery substances. This matter is called mitochondrial matrix. Thus option C is the correct answer.
