A Correct answer
Explanation

Messenger RNA (mRNA) typically constitutes 3-5% of total cellular RNA in most cells. It has the shortest half-life of all RNA types because it's continuously synthesized and degraded during protein synthesis. rRNA makes up about 80-85% while tRNA constitutes about 10-15% of total cellular RNA.
