Concept:The author stresses that protecting privacy in the digital age demands a balance between technology’s benefits and the right to privacy, achieved through awareness, regulation, and responsible behavior.Explanation:The passage explains that data is often collected without users’ knowledge, and many accept terms without reading them. Although privacy laws exist, their enforcement is weak. The author concludes that individuals must learn to balance convenience and privacy. This requires awareness of data practices, stricter regulation, and responsible digital habits. Option 3 (Awareness and responsible behavior) directly matches this idea. Option 1 (Avoiding all apps) is impractical and not suggested. Option 2 (Stronger surveillance tools) would increase monitoring, not protect privacy. Option 4 (Free mobile phones for all) is unrelated to the issue.Answer:Option 3: Awareness and responsible behavior.
