Solution

The correct option is A states that DNA is a template for all RNA production
During the transcription phase of the central dogma, DNA acts as the template for RNA synthesis. The RNA polymerase enzyme identifies the base on the DNA strand and adds a complementary base to the sequence. After transcription, translation of mRNA occurs that leads to the formation of the polypeptide sequence.
So, the correct option is 'states that DNA is a template for all RNA production'.
