failed

The answer is the third one (C): Nucleus.

Explanation for each option: A. Golgi apparatus - Incorrect. The Golgi apparatus is involved in modifying, sorting, and packaging proteins for secretion, but it does not provide instructions for protein assembly. B. Mitochondrion - Incorrect. The mitochondrion is the powerhouse of the cell, responsible for producing energy (ATP) through cellular respiration, but it does not give instructions for protein assembly. C. Nucleus - Correct. The nucleus contains the cell's genetic material (DNA), which provides the instructions for assembling proteins. The DNA is transcribed into mRNA, which then travels to the ribosomes to guide protein synthesis. D. Endoplasmic reticulum - Incorrect. The endoplasmic reticulum (ER) is involved in the synthesis of proteins and lipids, and the rough ER has ribosomes on its surface, but it does not provide the instructions for protein assembly.

Summary: The nucleus is the part of the cell that gives the ribosomes instructions on how to assemble a protein.
