Operon concept is applicable for all prokaryotes and some eukaryotes.
Explanation:
Operon concept was first proposed by Jacob and Monod in E.coli for lactose metabolism. It is a regulatory mechanism in prokaryotic cells where a group of genes is controlled by a single promoter and operator region. The genes in an operon are transcribed together to produce a single mRNA molecule, which is then translated into different proteins. This concept is applicable for all prokaryotic cells and some eukaryotic cells where gene regulation occurs through the operon mechanism.
Prokaryotes:
In prokaryotes, the operon concept is extensively used for gene regulation. The genes involved in metabolic pathways, such as lactose utilization, amino acid biosynthesis, and nitrogen fixation, are regulated by operons. The lac operon in E.coli is a classic example of operon regulation in prokaryotes.
Eukaryotes:
In eukaryotes, the operon concept is not as common as prokaryotes. However, some eukaryotic cells do use operons for gene regulation. The best-known example is the histone gene cluster, where a group of histone genes is regulated by a single promoter and enhancer region.
Conclusion:
In conclusion, the operon concept is a regulatory mechanism that is applicable for all prokaryotic cells and some eukaryotic cells. It allows for efficient gene regulation by coordinating the expression of multiple genes involved in a specific metabolic pathway.

No...I think option 'A' is correct.
Jacob and Monad study lactose metabolism in E.coli and proposed the Lac operon concept. The concept explains the transport and metabolism of lactose in Escherichia coli and many other enteric bacteria. The concept of Lac-operon is applicable to All prokaryotes.
So, the correct answer is 'All prokaryotes'.
