What does the role of customers in boycott of Jewish shops clarify?

Correct answer: Economic discrimination was also enforced through everyday behaviour

The direct answer is A: economic discrimination was also enforced through everyday behaviour. A boycott is not only an official order; it works when customers refuse to enter shops, buy goods, or support the targeted owners. The reasoning is: Nazi propaganda and policy marked Jewish businesses as unacceptable; customers avoided them or were pressured to avoid them; reduced sales damaged Jewish livelihoods; ordinary market behaviour therefore helped turn official prejudice into daily exclusion. Option A is correct because it shows that discrimination operated in streets, shops, and personal choices, not only in military offices. Option B is wrong because trade was not fully free when people were threatened, pressured, or guided by racist policy. Option C is wrong because a shop boycott is an economic and social action, not only a military policy. Option D is wrong because the boycott harmed Jewish business owners and offered them no extra protection. The role of customers does not mean all customers had equal freedom or intention, but it shows how a society can participate in persecution through routine actions. Memory cue: boycott plus customers means discrimination entering the marketplace.
