Answer:
Correct Answer: A
Solution:
Extracellular materials (also called Intercellular materials) are very important for cells because they surround the individual cells, separate them from each other and bind them together.
One or more types of specialized cells are set in specific extracellular materials to constitute a tissue.
Nature and amount of extracellular material vary from tissue to tissue.
In some tissues, it is limited to very thin layers whereas, in some it is quite vast and separates cells widely apart from one another.
