Explanation

An organism is a living being made up of one or more cells that can carry out the functions of life (such as using energy, growing, or reproducing).

Tissue is the group of cells that perform specific functions.

An organ is a collection of tissues that together form a functional unit specialized to perform a specific function.

The cell is the correct option as the cell is the building block of an organism. These cells are found in all living creatures. Some are single-celled, while others are multicellular. These give the body structure as well as nourishment.
