Earth and its atmosphere are continuously altered. Plate tectonics shift the continents, raise mountains and move the ocean floor while processes not fully understood alter the climate. Such constant change has characterized Earth since its beginning some 4 billion years ago.

Answer: b. removal of introns from mRNA
The process by which Ribosomes attached to ER or lying freely in the Cytoplasm synthesize proteins from the transcribed mRNA of the DNA is called Translation.
Explanation:
It is made up of three stages;
1. INITIATION;Options C mRNA binding to the ribosome
2. ELONGATION ;Option D joining large and small ribosomal subunits
3, TERMINATION;Option E chain termination at a stop codon
However, Introns are non coding region of RNA base sequence transcribed from the DNA, or sections of DNA encoding the RNA. It is an unwanted part which must be sliced out before translation. Therefore it is not a relevant steps of translation, and hence Option B is the wrong answer.
Note the coded part of RNA trancripts is called EXONS. this the part with the needed information.
