The answer is (c), the dado shapes the polymer into the desired profile.

The dado is a slot in the extrusion die that determines the cross-sectional shape of the extruded product. The dado is usually made of a hard material, such as steel or tungsten carbide, to resist wear.

The dado is typically tapered, so that the polymer is forced to flow into the desired profile. The angle of the taper and the width of the dado determine the thickness of the extruded product.

The dado is an important part of the extrusion process, as it determines the final shape of the product. The dado must be carefully designed to ensure that the product meets the desired specifications.

The other options are incorrect. The dado is not responsible for the fusion of the polymer, as this is done by the heat and pressure of the extrusion process. The dado also does not help in the distribution and dispersion of the materials, as this is done by the mixing screw in the extruder.
