A
Vacuole
B
Chloroplast
C
Centrosome
D
Nucleus
Explanation: 

Detailed explanation-1: -Chloroplasts contain green pigment called chlorophyll which helps in manufacture of food through the process of photosynthesis. Since, animals do not manufacture food so they do not need chloroplast. And hence, chloroplast is found only in plant cell.

Detailed explanation-2: -Chloroplasts can be found in all green tissues or cells of plants, although they are concentrated in the parenchyma cells of the leaf mesophyll. Note: One of the functions of such pigments is to absorb light energy for the photosynthesis process.

Detailed explanation-3: -Chloroplasts are found in plant cells only because chloroplasts contain chlorophyll which is essential for photosynthesis. Chlorophyll traps sunlight and uses it to prepare food for plants by the process of photosynthesis.

Detailed explanation-4: -Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells.
