Answer: (A)

Verified step by step guidance

1. Understand the basic definition of connective tissue: Connective tissue is one of the four main types of tissue in the body, and its primary function is to support, bind, and protect other tissues and organs.
2. Identify the key characteristic of connective tissue: Connective tissue is known for having a large amount of extracellular matrix, which is a network of proteins and other molecules that provide structural and biochemical support to the surrounding cells.
3. Differentiate connective tissue from other tissue types: Unlike epithelial tissue, which is composed of tightly packed cells, connective tissue has fewer cells and more extracellular matrix.
4. Consider the function of connective tissue: While some tissues, like nervous tissue, are involved in transmitting electrical impulses, connective tissue primarily serves structural and supportive roles.
5. Review the options given in the problem: The correct characteristic of connective tissue is that it contains a large amount of extracellular matrix, distinguishing it from the other options provided.
