The Correct Option is D
Approach Solution - 1
Molecular assemblies are large organised sets of molecular units that make up parts of organelles. For example one common macromolecular assembly is the microtubule which is important in forming structure in the cell related to maintaining the cell structure or related to cell movement. The cell (plasma) membrane that surrounds many organelles and the cell is a highly organised molecular assembly.

Biological organization refers to the hierarchy of living organisms from small to large scale.
It begins at the submicroscopic molecular level, when proteins, lipids, and carbohydrates are arranged to form organelles.
The molecules, organelles, cells, tissues, organs, organ system, organism, population, community, ecosystem, and biosphere are the stages of biological organization in ascending order.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
