Explanation:

In a research process to determine if a new refrigerator model is more efficient than the old one, the first step is to formulate a testable claim (hypothesis) about the efficiency of the new model. Choosing a sample (option 2) comes after defining the claim. Making initial conclusions (options 3 and 4) is premature as conclusions are drawn after testing, not at the start. So the correct first step is to write a testable claim about the new model's efficiency.

Answer:

A. Write a claim about the efficiency of the new model that can be tested.
