Solution

The correct option is A Euglena
Euglena undergoes asexual reproduction by binary fission. Binary fission in Euglena is longitudinal, where division occurs along the longitudinal axis. It is the process of mitosis and in this, cell organelles are duplicated and two sets separate to form two daughter cells.
Plasmodium reproduces by multiple fission in which nucleus divides repeatedly forming many nuclei.
Planaria reproduces by fragmentation.
Paramecium multiples by transverse binary fission.
Thus, the correct answer is option (A).
