All of these are correct.

Detailed explanation-1: -mRNA is the form of RNA which helps in encoding the message coming from the DNA to form proteins. Then it transports the gathered data into the cell where proteins are assembled and generated. So, for these reasons RNA necessary to act as a messenger.
Detailed explanation-2: -The role of mRNA is to carry protein information from the DNA in a cell’s nucleus to the cell’s cytoplasm (watery interior), where the protein-making machinery reads the mRNA sequence and translates each three-base codon into its corresponding amino acid in a growing protein chain.
Detailed explanation-3: -mRNA is the molecule that carries the message contained within DNA to the ribosome. Ribosomes are where proteins are produced. mRNA is important because ribosomes can’t reach the DNA inside our cell nucleus, which is the location inside the cell where DNA is housed.
