• D. Tissue → Cell → Organ → Organism

Answer: (A)

Verified step by step guidance

1. Step 1: Understand the concept of biological organization. Biological organization refers to the hierarchy of complex biological structures and systems that define life, ranging from the smallest unit (cell) to the entire organism.
2. Step 2: Define each level of biological organization: - Cell: The smallest unit of life capable of performing all life processes. - Tissue: A group of similar cells working together to perform a specific function. - Organ: A structure composed of multiple tissues working together to perform a specific function. - Organism: A complete living entity made up of organ systems working together.
3. Step 3: Arrange the levels logically from the simplest to the most complex. Start with the cell, as it is the basic unit of life, followed by tissue, organ, and finally organism, which represents the highest level of organization.
4. Step 4: Compare the given options to the correct logical sequence: Cell → Tissue → Organ → Organism. Identify which option matches this sequence.
5. Step 5: Eliminate incorrect options by checking if they disrupt the logical progression from the simplest (cell) to the most complex (organism). Select the option that correctly arranges the levels of biological organization.
