Answer: The correct answer is-
C) regulates all cell activity:nucleus
DNA (deoxyribonucleic acid) is the genetic material of living organisms. It is present inside nucleus in eukaryotic organisms (such as plants and animals).
It possesses genetic information in the form of nucleotide sequences (that form code for specific proteins). It helps in regulating all the essential cellular activities as it is transcribed and translated to produced desired protein products.
The protein produced are important in driving the cellular processes (such as cell growth, cell division, interaction with other cells) .
Thus, option C) is the right answer.
