Solution
The correct option is B Mesophyl layer
Scleroblasts are the skeleton manufacturing cells and may be calcoblasts, silicoblasts or spngioblasts depending upon the skeletal element these are producing. Scleroblasts are present in Mesenchyme. Mesenchyme is also known as mesophyl or mesoglea. It is the inter connecting proteinaceous gelatinous matrix present between the outer layer pinacoderm and inner layer choanoderm in the body wall of sponges.Hence, scleroblasts of sponges occur in Mesophyl layer.So, the correct answer is 'Mesophyl layer'.
