<em>True: </em><u>b) Tissue is a group of specialized cells that work together for a common function and form organs.</u>
Explanation:
Cells are the smallest units of life, they may be either unicellular or multicellular. Unicellular organs have a single cell capable of carrying out all of the functions necessary for its survival. Multicellular organisms are more complex, and require the work of multiple different cell types.

Groups of specialized cell types form tissue; these each have varying functions over time. Organs consist of two or more tissue types that are specifically organized to carry out a function.
