Verified step by step guidance

1. Step 1: Understand the concept of biological organization, which refers to the hierarchy of structural levels in living organisms, starting from the smallest unit to the largest.
2. Step 2: Define each level of biological organization: Molecule (smallest chemical unit), Cell (basic unit of life), Tissue (group of similar cells performing a specific function), Organ (group of tissues working together), and Organism (individual living entity).
3. Step 3: Recognize that the correct order of biological organization is based on increasing complexity, starting from the smallest unit (molecule) and progressing to the largest (organism).
4. Step 4: Compare the given options to identify the sequence that matches the correct order: Molecule → Cell → Tissue → Organ → Organism.
5. Step 5: Eliminate incorrect options by checking if they follow the logical progression of biological organization, ensuring the smallest unit comes first and the largest unit comes last.
