Explanation:

The correct answer will be option-D

Explanation:

The food contains an organic compound which stores energy in the form of their chemical bonds like glucose.  

The energy stored in the glucose and other biomolecule is converted to the more convenient molecule called ATP which can be utilized by the organism.

The organelle which is involved with the conversion of the stored chemical energy from the food to the usable molecule is called "mitochondria".

The process by which the glucose is converted to usable form ATP is known as cellular respiration.

Thus, option-D is the correct answer.
