If a specified development impacts on a heritage resource, … a. an archaeological heritage assessment report is required in terms of the National Heritage Resources Act b. an environmental assessment is required in terms of the National Heritage R

The correct answer would typically be: **a. an archaeological heritage assessment report is required in terms of the National Heritage Resources Act.** This is because the National Heritage Resources Act focuses specifically on the conservation of heritage resources, and any development that impacts such resources would necessitate an assessment to ensure compliance with heritage conservation standards. However, context is essential, and depending on the specifics of the development and the environment, other assessments (such as those mentioned in options c and d) may also be required under the National Environmental Management Act.
