The correct answer is **b. Elastomeric**.
Elastomeric impression materials, which include polyether and addition-cure silicone (PVS), are typically used for final impressions because of their dimensional stability and accuracy. Alginate is often used for preliminary impressions, while acrylic is used for making base plates and occlusal rims. However, elastomeric materials are specifically preferred for creating the final impressions needed for precise restorations or prosthetics.
