Answer: (B)

Verified step by step guidance

1. Step 1: Begin by understanding the levels of biological organization, which range from the smallest unit (cell) to the largest (organism). These levels include: cell, tissue, organ, organ system, and organism.
2. Step 2: Recall the definition of a tissue. A tissue is a group of similar cells that work together to perform a specific function. For example, muscle tissue consists of muscle cells that contract to enable movement.
3. Step 3: Compare the definition of tissue with the other options provided: Organ (a structure made of multiple tissues working together), Organ System (a group of organs working together), and Organism (an individual living entity).
4. Step 4: Identify that the question specifically asks for the level of organization where similar cells work together, which matches the definition of tissue.
5. Step 5: Conclude that the correct answer is 'Tissue,' as it represents the level of biological organization described in the problem.
