Chondroitin sulfate: is a highly polar molecule with many negative charges. Because of its polar nature, it has a strong affinity with water. In solution, it is heavily hydrated, which increases the overall volume of the complex, in contrast to its close-packed form when it is a dehydrated solid.
vs.
"It adheres to positively charged molecules of collagen in the extracellular matrix" (Choice A) may be a factual statement, but it does not explain the reorientation of chondroitin sulfate molecules when hydrated vs. dehydrated!!
