A
DNA
B
cytoplasm
C
organelle
D
nucleus
Explanation: 

Detailed explanation-1: -The cytoplasm, or cell fluid, is made up of a jelly-like substance (cytosol) and within that, the organelles. The organelles are the cell’s organs. The cytoplasm is often colourless and is surrounded by the cell membrane which keeps the contents within the cell.

Detailed explanation-2: -Cytoplasm is a thick solution that fills each cell. It is enclosed by the cell membrane. It is made up of water, salts and proteins. In eukaryotic cells, the cytoplasm includes all of the material inside the cell and outside of the nucleus.

Detailed explanation-3: -In both prokaryotic and eukaryotic cells, a semi-fluid matrix called cytoplasm occupies the volume of the cell. This is the main arena of cellular activities in both the plant and animal cells. Various chemical reactions occur in it to keep the cell in the living state.

Detailed explanation-4: -Complete solution: The term ‘Cytoplasm’ was given by German scientist Eduard Strasburger for the jelly-like part of a cell between the nucleus and cell membrane in 1882. The cytoplasm is divided into two parts, namely, Cytosol and Protoplasm.
