Solution

The correct option is A

Division of labour


A cell is the basic structural and functional unit of all organisms.A group of cells which is formed to carry out specific task is called a tissue.Formation of tissues is the first step towards division of labour in multicellular animals. Subsequently, a group of tissues forms an organ and a group of organs forms the organ system.Division of labour increases overall efficiency because some cells can now dedicate themselves to one particular function.
