Explanation / Answer

30)

The correct answer is option D that is all of these should be used collectively for proper identification of bacteria.

Gram staining is necessary to tell whether the bacteria is of gram positive or gram negative species.

Cellular morphology and colony arrangements are also very important.

Biochemical properties are also necessary to identify the bacteria.

And that is why all these tests are cumulatively very important to identify the bacteria.
