Protect mRNA from degradation and enhance translation

Explanation:

In Eukaryotes, the DNA replication and transcription process take place in the nucleus of the cell. The mRNA molecule formed by the process of transcription undergoes post-transcriptional modification which are the capping at 5'end and tailing at 3'end.

These modifications are done in order to protect the mRNA from the reducing environment of the cytoplasm and also they enhance the process of translation.

Thus, the selected option is correct.
