Concept:Binary fission is an asexual reproductive method in which a single organism divides into two genetically identical daughter cells.
Explanation:The diagram shows a parent cell dividing into two equal halves.
This process starts with the replication of the genetic material.
The cell then splits into two daughter cells.
No gametes are involved, so the reproduction is asexual.
Budding produces an outgrowth that detaches later.
Grafting and vegetative propagation are methods used in plants, not single-celled organisms.
Therefore, the illustrated process is binary fission.
Answer:B. binary fission
