A
nucleus
B
chloroplast
C
cell membrane
D
mitochondria
Explanation: 

Detailed explanation-1: -All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide. Prokaryotes often have appendages (protrusions) on their surface. Flagella and some pili are used for locomotion, fimbriae help the cell stick to a surface, and sex pili are used for DNA exchange.

Detailed explanation-2: -All prokaryotes have a cell membrane and cytoplasm, and most also have a cell wall. As with eukaryotic cells, the plasma membrane may not be obvious under the microscope, but the cell wall should be visible. Most prokaryotic cells are 10-100 times smaller than eukaryotic cells, although there are exceptions to this.
