C Correct answer
Explanation

Cell theory states that all living organisms are composed of cells, and the cell is the basic structural and functional unit of life. This is a fundamental principle - cells arise only from pre-existing cells (not spontaneously), organelles cannot survive independently, and not all cells have cell walls (animal cells lack them).
