The correct answer is B. Are specialized
Step-by-step explanation:
In biology, cells are the basic unit of life because they are necessary for basic functions such as obtaining nutrients and reproducing. Additionally, many cells perform specific functions for example, spermatozoids are essential for reproduction, while nerve cells are the cells that transmit and receive electrical impulses; these are known as specialized cells. Thus, cells that perform a specific function in an organism are specialized as each type of cell is essential for a specific function and its structure is designed for this.
