Solution

The correct option is C Capping
The process of addition of methyl GPT at the $5^{'}$ end of hnRNA is known as capping. Enzyme guanly transferase catalyses this process.
Cap is essential for the formation of mRNA-Ribosome complex. Translation is not possible if cap is lacking, because cap is identified by $18$ SrRNA of ribosome unity.
