Answer 1

The correct option is D Thoracic muscles of birds

Mitochondria is a double membrane-bound organelle found in most eukaryotic organisms. The roles of mitochondria are to produce the energy currency of the cell. As it provides the energy it is present in thoracic muscles of birds because these muscles help in flight adaptations in birds. Flying birds require more energy which is supplied to them by mitochondria.
