The standard of care in product design/manufacturing involves designing for safe use, identifying hazards, assessing risks, applying appropriate standards, and implementing controls, testing, and warnings. Options A, B, and D are core responsibilities: ensuring safe design and manufacture (A), applying relevant codes/standards and good practice (B), and performing hazard analysis and risk assessment (D). Option C is not a valid safety responsibility: businesses and professionals cannot “eliminate” liability simply by legal caveats or disclaimers, especially where negligence, unsafe products, or statutory duties are involved. NPPE liability themes emphasize that disclaimers may be limited, may not protect against negligence causing harm, and do not replace the obligation to meet the standard of care. Therefore, C is the task that is not part of responsible design/manufacturing practice.
