Correct Answer:
A. Design
The standard components of a curriculum typically include Objectives (what students should learn), Contents (the subject matter), Learning Experiences/Methods (how content is delivered), and Evaluation (how learning is assessed). Design, while crucial, refers to the systematic process or framework used to organize and structure these components. It is the blueprint or plan, rather than a distinct, substantive element within the curriculum itself like the others. Therefore, 'Design' is not considered a component in the same way as objectives, content, or evaluation, which are the core elements that constitute the curriculum's substance and assessment.
