Which of the following reflects a proactive process aimed at preventing defects?

The correct choice reflects a proactive process aimed at preventing defects, which is encapsulated in the principle of Quality Assurance. Quality Assurance involves systematic activities and structured processes implemented throughout the development lifecycle to ensure that the product meets the specified requirements and standards before it reaches the customer.

This proactive approach emphasizes planning, systematic monitoring, and improving processes to prevent defects from occurring in the first place. In contrast, other concepts like Quality Control focus primarily on identifying defects in the final product, rather than preventing them during the development stages. Quality Evaluation and Quality Improvement are also important aspects but do not specifically center on the proactive prevention of defects in the way Quality Assurance does.
