Genetic engineering mainly aims at the transfer of genes of desired protein products between the organisms. Lysosomes are the suicidal bags of cell that digest and remove the wear and tear organelles and molecules from the cell. Golgi body consist of flattened sacs stacked on each other, that serve to processes secretory and synthetic products from the ER and then transport the finished products into cell part or secretes them to the outside of the cell. Mitochondria are double membrane bound eukaryotic cell organelles that serve as the site for cellular respiration, produce an enormous amount of energy and therefore are also known as a power house of cell. Plasmids are low molecular weight extrachromosomal DNA that carries origin of replication, restriction sites and selectable markers to confer readily selectable phenotypic traits on host cells. Plasmids require very few genes for their own replication and rest of it can be deleted and foreign sequences can be added to the plasmid which in turn makes them a suitable candidate to serve as a vector for gene transfer. Thus, the correct answer is option C.
