Explanation:

To determine the aspects of cell theory, we analyze each statement:

• Statement I: All living organisms are made of one or more cells. This is a core part of cell theory.
• Statement II: The cell is the basic unit of structure and organization in living things. This is also a fundamental aspect of cell theory.
• Statement III: All matter is made of cells. This is incorrect because non - living matter (like rocks, water) is not made of cells.
• Statement IV: All cells come from pre - existing cells. This is a key part of cell theory.

So, the correct aspects are I, II, and IV.

Answer:

D. I, II, and IV only
