The correct option is C.
The nucleus is the control center of the eurkaryotic cells. The DNA, which is the genetic material of the cell is localized inside the nucleus. The amount of nucleus found in different cells of the body differs; some cells have one nucleus, some have multiple nucleus while some do not have nucleus at all, a good example of this are the red blood cells. The muscle cells are typical examples of cells that have multiple nuclei.
The muscle cells are attached to the skeleton and they facilitate movement in vertebrates. Because of its functions and its constant need for repair, due to wear and tear, the muscle cells need huge quantity of protein, that are processed at accelerated speed for proper functioning of the muscles cells. The amount of protein needed is greater than what one nucleus can efficiently handled, thus, the need for many nuclei. The DNA, which is found in the nucleus is responsible for the transcription of RNA, which is then transported to the cytoplasm for the process of protein translation.
