Explanation:

The population is all cell phones produced by a company. The question "What is the average number of cell phones owned by a family of four?" is about family cell phone ownership, not the produced phones. "Who is the typical user..." is about users, not the phones produced. "How many minutes..." is about teen phone usage, not the phones produced. "What percentage of cell phones made by the company are defective?" is about the quality of the produced cell phones, which directly relates to the population of all cell phones produced by the company.

Answer:

The best survey question is: What percentage of cell phones made by the company are defective? (The option with this text, assuming the radio buttons correspond to this question as the third option from the left in the visible text, but based on the content, the question "What percentage of cell phones made by the company are defective?" is the correct one for the population of all cell phones produced by a company.)
