• B. replication
• C. transduction
• D. transcription

Answer: (B)

replication

Answer 2

DNA multiplication or duplication of DNA takes place by replication. It takes place during S-phase of interphase during cell-cycle. DNA replication is semi-conservative was strongly evidenced by Mathew Meselson and Franklin Stahl in 1958 in $E$. coli.
Transcription is the mode by which DNA passes its genetic information to $m$ RNA. It is the first step in protein synthesis which takes place in nucleus of eukaryotic cells.
Translation is the synthesis of a chain of polypeptide by $m R N A$. It is the process when protein synthesis takes place at the site of ribosomes. It involves 3 steps initiation, elongation and termination.
Transduction is the transfer of genes from one bacterial cell to another by means of a virus. Transduction was discovered by Zinder and Lederberg in 1952 .
