Hint:Paramecium is a unicellular aquatic organism in which only one cell performs all the vital functions which are important for the survival of living organisms.

Complete step by step answer:
1 :- Paramecium is a unicellular aquatic organism which belongs to the protista group.
2 :- Paramecium follows holozoic mode of nutrition. In holozoic mode of nutrition it simply engulfed the food item from the surrounding.
3 :- Paramecium consist of a large number of cilia on the whole body which swap the water of the surrounding towards it so that any food item present in nearby area can easily come closer to the paramecium.
4 :- when that food item comes into closure then It will transfer into the cell from the cell mouth followed by the cell groove.
5 :- These cilia also help in the movement of the cell in a straight line so that the cell can easily come near to the target site.
6 :- As paramecium is an aquatic organism so to maintain the osmotic pressure and for osmoregulation contractile vacuole is an important cell organelle.
7 :- when unfavourable conditions are present near the paramecium then it have a special quality to form a cyst over it for protection.
So from the above detail of paramecium we come to know that the paramecium don’t have any pseudopodia for prey capturing and food requirement.

So option D is correct.

Note:
Paramecium is a slipper shaped organism and similar type of organization as that of amoeba.
