Solution
The correct option is A Rudolf Virchow
Cell theory was proposed by a German botanist, Matthias Schleiden and English zoologist, Theodor Schwann in the year 1839. The cell theory states
1) Cells are the building blocks of living organisms.
2) All living organisms are composed of cells and a cell is the basic structural and functional unit
Later on, Rudolf Virchow added a new point in cell theory that 'all cells arise from pre-existing cells'.
So, the correct answer is option B.
