Answer: The correct answer is C) DNA.
DNA ( deoxyribonucleic acid) is the genetic material of all life forms. It carries information in the form of nucleotide sequences. DNA is transcribed into mRNA ( messanger RNA), which is then translated into specific proteins. mRNA contains sequences in the form of codon ( a triplet code of nitrogenous base for specific amino acid)
As mRNA is transcribed from DNA. Thus, instructions for making proteins originally comes from DNA.
According to the Central Dogma, genetic information is passed in this order-
DNA→ mRNA→ Protein
