The Correct Answer is C

Correct Answer is B
Explanation
A. Drying time is typically shorter with a synthetic cast compared to a plaster cast. Synthetic casts are designed to set faster, reducing the time the patient needs to remain immobilized during casting.
B. A synthetic cast is generally lighter in weight than a plaster cast. This can be more comfortable for the patient and may reduce the risk of muscle atrophy or discomfort associated with the cast's weight.
C. A plaster cast does not necessarily require expensive equipment for application, and both plaster and synthetic casts can be applied using relatively simple and cost-effective methods.
D. The effectiveness of immobilization is not significantly different between plaster and synthetic casts. Both types of casts can provide adequate immobilization for bone fractures, and the choice between them may depend on factors like patient preference, the type of fracture, and other clinical considerations.
