The answer is : A model could be used to test his design in a lab. Marty is developing a new way to heat an airplane's windshield to prevent it from accumulating ice when in flight. A thin layer of clear, conductive material is injected between two layers of thick windshield plastic. A very small electric current is run through the inner material to keep the plastic layers warm. The model that could help Marty develop his design is the kind of model that could be used to test his design in a lab.
Answer:
B) A model could be used to test his design in a lab
Explanation:
The models in a laboratory scale are used usually to test new methods or technologies (like the one Marty is developing) to see if they work or what adjustments they required to take them to real scale.
