Explanation:

To determine the function of mRNA, we analyze each option:

• The first option: mRNA is transcribed from DNA in the nucleus and then travels to the ribosome (in the cytoplasm) to carry the genetic message for protein synthesis. This matches the known function of mRNA.
• The second option: mRNA does not stay inside the nucleus; it moves to the ribosome, so this is incorrect.
• The third option: DNA provides instructions to mRNA (through transcription), not the other way around, so this is incorrect.

Answer:

A. It takes the DNA message (instructions) out of the nucleus to the ribosome
