The gelatinous extracellular matrix found in sponges is called mesohyle or mesenchyme which contains fibrils, skeletal elements, and ameboid cells.

Option B, collagen, is also found in the extracellular matrix of sponges, but it is not the only component. Option C, pinacoderm, refers to the outer epithelial layer of cells in sponges, and not to the mesohyl.
