The following choices are provided;

(1) tissues → cells → organelles → organs

(2) cells → organelles → organs → organism

(3) organelles → cells → tissues → organs

(4) organism → cells → tissues → organelles


The answer is; (3)

Each organelle performs a particular function in cells. Cells are the basic unit of organisms and are complete self-sustaining life entities. Many cells, differentiated to perform a particular function, make up a tissue (such as bone, muscle tissues). Many tissues come together to make up an organ such as the heart that is composed of cardiac tissue, nerve tissue, blood tissue, etcetera.
