Dioxy-ribo nucleic acid/dna
Amoeba acquires it food by endocytosis, that is, a small region in the plasma membrane which ultimately forms a intra-cellular membrane-bound vescicle. It engulfs it food using its pseudopodia (temporary protrusion of the surface of the amoeboid cell used for feeding and movement) and forms a vacuole around it. When the food is already trapped inside, it releases a digestive enzyme to digest it. Intake of liquid particles is pinocytosis (cell drinking) while intake of solid particles is phagocytosis (cell eating).
Probably if there are not enough plants in that area
That is binary fission, 'cause in this process, chromosome number doubles to it's original value whereas in meiosis it gets halved.
In short, Your Answer would be Option D
Hope this helps!
