Read the following statements with respect to given diagram and select the correct option. 
(A) The inner compartment of the organelle is filled with a dense heterogeneous substance called the matrix.
(B) The number of this organelle per cell is variable depending on the physiological activity of the cells.
(C) The inner membrane forms a number of infoldings called the cisternae towards the matrix.
(D) The matrix of this organelle also possess circular ds DNA molecule, few RNA molecules, ribosomes and the components required for the synthesis of proteins.
(E) They are called as ‘Power houses of the cell’ as they produces cellular energy in the form of ATP by utilising light energy.
A, C and E - incorrect, B and D - correct
(A) Correct. The inner compartment is the matrix, a dense substance.
(B) Correct. Number of mitochondria varies with energy demand of the cell.
(C) Incorrect. Inner membrane forms cristae, not cisternae (cisternae belong to ER/Golgi).
(D) Correct. Matrix contains circular DNA, RNA, ribosomes, enabling partial protein synthesis.
(E) Incorrect. ATP is produced using energy from oxidation of nutrients, not light energy.
