The correct answer is C. Mitosis.
Mitosis is a type of cell division that results in two identical daughter cells. It is the process by which somatic cells (cells other than gametes) grow and divide, producing two identical daughter cells. Mitosis is a continuous process, but it can be divided into four phases: prophase, metaphase, anaphase, and telophase.
In prophase, the chromosomes condense and become visible. The nuclear envelope breaks down, and the spindle fibers form.
In metaphase, the chromosomes line up at the center of the cell.
In anaphase, the sister chromatids (the two identical copies of each chromosome) separate and are pulled to opposite poles of the cell.
In telophase, the chromosomes decondense, the nuclear envelope reforms, and the spindle fibers disappear. The two daughter cells are now complete.
Heterosis is the increased vigor and productivity of a hybrid over either of its parents. It is often the result of combining the best traits of two different parents.
Fusion is the process of combining two or more cells into one. It is a common process in cell biology, and it is used in a variety of applications, such as cloning and gene therapy.
None of these options are correct.
