A
Vacuole
B
Cell
C
Golgi Body
D
Ribosome
Explanation: 

Detailed explanation-1: -ribosome – A small grain-like structure in the cytoplasm of a cell where proteins are made.

Detailed explanation-2: -Ribosomes are the sites in a cell in which protein synthesis takes place.

Detailed explanation-3: -A ribosome is an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell. The ribosome reads the messenger RNA (mRNA) sequence and translates that genetic code into a specified string of amino acids, which grow into long chains that fold to form proteins.

Detailed explanation-4: -Ribosomes are mainly found bound to the endoplasmic reticulum and the nuclear envelope, as well as freely scattered throughout the cytoplasm, depending upon whether the cell is plant, animal, or bacteria.

Detailed explanation-5: -How do you make a ribosome? Some chromosomes have sections of DNA that encode ribosomal RNA, a type of structural RNA that combines with proteins to make the ribosome. In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome.
