Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Transduction was first of all reported by N D Zinder and Lederberg $ (1952)$ in bacteria Salmonella typhimurium. In this process, DNA of a bacterial cell is transferred into another bacterial cell through bacteriophage a kind of virus, which is parasitic upon bacteria.

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
