Ribosomes are the site of protein synthesis in cells. They are small, complex structures composed of RNA and protein that bind to mRNA and use it as a template to synthesize proteins. Hence option 2 is the correct answer.

Option(1) Nucleus is the hereditary centre and it is not the site of protein synthesis. Hence option 1 is incorrect.

Option(3)  Mitochondria is the power house of the cell and it is not the site of protein synthesis. Hence option 3 is incorrect.

Option(4) Smooth endoplamic reticulum is concerned with lipid synthesis and rough lodges ribosomes in which protein synthesis occurs and it is not directly involved in protein synthesis. Hence option 4 is incorrect.
