AMonera
BProtista
Correct Answer
CFungi
DNone of these

Solution

Five kingdom classification was proposed by R.H. Whittaker. According to this organisms has been divided into five kingdoms Monera, Protista, Fungi, Animalia, Plantae. Organisms are divided on the basis of different characters like cell boundary, shape, type of nutrition etc.
According to R.H. Whittaker classification-
Monera has a cell wall. It is made up of polysaccharides i.e. peptidoglycan
Fungi have a cell wall. It is made up of chitin.
Protista has no well-defined boundaries.
So, the correct answer is 'Protista'.
