B Correct answer
Explanation

This is the correct matching. Cells were first discovered by Robert Hooke in 1665. Leeuwenhoek observed free cells like bacteria for the first time. Robert Brown discovered the nucleus in the cell. J.E. Purkinje coined the term ‘protoplasm’ for the fluid substance of the cell. M. Schleiden and T. Schwann proposed the cell theory that all plants and animals are composed of cells and that cell is the basic unit of life.
