The right option is; B. Duplication.
Duplication is not included during the process of RNA transcription. Transcription is the first phase in gene expression in which a gene's DNA sequence is copied to form an RNA (particularly mRNA) molecule. The main transcription enzyme in this process is RNA polymerase which functions by joining nucleotides together to form a complementary, antiparallel RNA strand. RNA transcription occurs in three major steps which are; initiation, elongation, and termination.
