The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
Transduction is a mechanism of bacterial horizontal gene transfer mediated by biological viral vectors.

Step 2: Detailed Explanation:

Transduction (discovered by Norton Zinder and Joshua Lederberg in 1952 in Salmonella typhimurium) is the process by which bacterial host chromosomal or plasmid DNA is encapsulated into a bacteriophage (bacterial virus) capsid head during viral assembly and transferred into a recipient bacterial cell upon subsequent infection.

Step 3: Final Answer:

Therefore, transduction in bacteria is mediated through a virus (bacteriophage).
