If a law improves product safety, what benefit will consumers get?

Correct answer: They will get safer products

The direct answer is B, consumers will get safer products. A product-safety law sets standards or duties intended to reduce risks from defective, dangerous, or improperly labelled products. The reasoning is: the law requires safety measures; the producer tests, designs, labels, or controls the product accordingly; unsafe products are less likely to reach consumers or cause harm; consumers receive better protection. Option A, changing customer age, has no connection with product safety. Option B is correct because safer products directly protect consumers’ health, life, property, and interests. Option C, making weather stable, is impossible through an ordinary product-safety law and belongs to the natural environment. Option D, making machines free, is a price or ownership issue, not the purpose of safety regulation. A safety law may increase business duties or compliance costs, but its consumer benefit is reduced risk and greater confidence. Exam cue: product safety means protection from harm, not free goods or changed weather.
