Solution

The correct option is B transcription
The process of copying genetic information from one strand of the DNA into RNA is termed as transcription. Unlike the process of replication, which once sets in, the total DNA of an organism gets duplicated, in transcription only a segment of DNA and only one of the strands is copied into RNA.
