The correct answer is B. Cells divide, producing more cells.
Explanation
The cell is the basic unit of life for all living things. Likewise, it is a form of classification for them since living organisms can be classified according to the number of cells they have unicellular (a single cell), multicellular (more than one cell). In organisms that have more than one cell, they divide to produce more cells and form the organs and tissues themselves. Cell division can occur from two processes that are mitosis and meiosis in which two and four cells are produced respectively. According to the above, the correct answer is B. Cells divide and producing more cells.
