Answer: (B)

Verified step by step guidance

1. Understand the concept of ground substance in connective tissues. Ground substance is the non-cellular component of the extracellular matrix, which provides support and binds cells together.
2. Identify the types of connective tissues mentioned: adipose tissue, areolar tissue, cartilage, and bone. Each has different characteristics and functions.
3. Adipose tissue primarily stores fat and has a soft, gel-like ground substance, making it less solid compared to other connective tissues.
4. Areolar tissue is a loose connective tissue with a gel-like ground substance, providing flexibility and cushioning, but not as solid as bone or cartilage.
5. Cartilage has a firm but flexible ground substance due to the presence of chondroitin sulfate, while bone has the most solid ground substance due to the mineralization with calcium phosphate, making it rigid and strong.
