This tissue consists of a collection of cells surrounded by , which is composed of thread-like and which varies in consistency.

The correct terms would be - 1) extracellular matrix 2) protein fibers 3) ground substances.

Explanation:

Connective tissue is one of the four animal tissues which are made up of the different type of cells but the most common cell is fibroblast that makes both protein fiber and ground substances. These cells are surrounded by the extracellular matrix.

The ground substance is amorphous in nature and varies in the consistency and protein fibers are thread-like structure. Both cells are synthesized by the fibroblast.

Thus, the correct answer is - 1) extracellular matrix 2) protein fibers 3) ground substances.
