The correct option is C Lysosmes
A lysosome is a membrane-bound organelle found in nearly all animal cells. They are tiny sacs filled with protein digesting enzymes. The proteins which are no longer required by the cell are broken down into their building blocks (amino acids) in the lysosomes. These building blocks can again be used by the cell to make new proteins. Hence, lysosome is also called the waste treatment plant or the 'recycle bin' of a cell.
