The correct sequence in increasing complexity is Protein – Tissue – Organ – Organism. This corresponds to option D.

Biological organization follows a hierarchical structure, starting from molecules and progressing to larger, more complex levels. Proteins are complex molecules. Tissues are groups of similar cells. Organs are composed of different tissues working together. An organism is a complete living being made up of organ systems (which are made of organs).

The general hierarchy of biological organization is: atoms < molecules < organelles < cells < tissues < organs < organ systems < organism < population < community < ecosystem < biosphere. Proteins are a type of molecule.
