Answer:
The correct answer will be option-B
Step-by-step explanation:
The nucleus is a double membrane organelle which encloses the genetic material of the cell. The nucleus provides several functions to the cell as it protects the DNA from the attack of the exonuclease and from the acidic environment of the cytoplasm.
Since the nucleus encloses the genetic material or the coding material which provides instructions to the cell, therefore, the nucleus is also known as the control center of the cell.
Thus, the nucleus is the correct answer.
