The correct option is D All of the above
Bacterial culture is first required to be diluted so that it is possible to count the colonies when it is developed in a petri dish as it is easy to count bacterial colony with naked eyes than to count every single bacteria.
Bacterial culture is developed on a solid medium known as agar in a petri dish.
So, the correct answer is 'All of the above'.
