Solution
The correct option is D Euglena, Paramecium, Amoeba
As shown in figure 1, represents binary fission in Euglena. Euglena divides longitudinally, beginning at the front end of the cell, with the duplication of flagellar processes, gullet, and stigma. Presently, a cleavage forms in the anterior, and a V-shaped bifurcation gradually moves toward the posterior, until the two halves are entirely separated.
As shown in figure 2- In the paramecium, the macronucleus splits by a type of amitosis, and the micronuclei undergo mitosis. The cell then divides transversally, and each new cell obtains a copy of the micronucleus and the macronucleus.As shown in figure 3 amoeba after replicating its genetic material through mitotic division, the cell divides into two equal sized daughter cells.So, the correct answer is 'Euglena, Paramecium, Amoeba'
