In which situation can both the Right against Exploitation and criminal law become active?

Correct answer: A trafficking gang sells people and forces them to work

The direct answer is A: a trafficking gang that sells people and forces them to work can activate both protection against exploitation and criminal law. The fact chain is: people are treated as goods or controlled; they are forced into labour; trafficking and forced labour violate constitutional protection against exploitation; the organized selling and coercion can also constitute criminal offences. Option A is correct. Option B, preparing for an examination, is ordinary education and has no exploitation clue. Option C, writing an article, is expression and normally a lawful activity. Option D, travelling with a ticket, is lawful travel and shows no force or trafficking. The two legal ideas are connected but not identical: a constitutional right protects the person, while criminal law may punish the offenders. Do not assume every disagreement or difficult activity is a crime; look for trafficking, force, sale, and exploitation together.
