d. build his tree house out of the material that seems the strongest, and then test the material with water, ice, and wind.

Explanation:

To choose a durable building material for a tree - house that can withstand rain, snow, and wind, building multiple models with different materials and testing them against these elements is the best approach. Option A does this by building several models out of different materials and seeing which holds up best to wind, water, and ice. Option B tests different parts of a single house made of multiple materials rather than the overall durability of different materials. Option C only tests one material against cold and not all the elements. Option D starts with an assumed - strong material without comparing it to others.

Answer:

A. Build several models of his tree house out of different materials, and see which model holds up best to wind, water, and ice.
