In which situation will quality control system of an enterprise be useful?

Correct answer: In maintaining product safety and standards

The direct answer is A: maintaining product safety and standards. Quality control means checking materials, methods and finished products so that they meet the required level of safety, performance and consistency. In an enterprise, this may involve setting standards, inspecting inputs, testing products, recording results and correcting problems. This protects consumers and builds trust in the business. Option A is correct because safety and standards are the central purposes of quality control. Option B, hiding all complaints, is wrong because complaints can reveal defects and should be examined honestly. Option C, using wrong material, is wrong because unsuitable material may reduce quality or create safety risks. Option D, not keeping records, is wrong because records help trace problems, compare results and prove that checks were made. Quality control does not mean pretending that no problem exists; it means finding and correcting problems systematically. Memory cue: quality control asks, “Is it safe, standard and reliable?”
