Correct option is D
The correct answer is Preparing a design, preparing a blueprint, writing and editing the questions, writing the marking scheme.
At first, the design of the question paper needs to be prepared. Secondly one has to make a blueprint of that question paper. Blueprint is the matrix or chart reporting the number and type of test questions represented across the topics in the content area, consistent with learning objective and relative weight on the test given to each topic. In the next step, writing and editing take place. And lastly, a good marking scheme needs to be prepared. A marking scheme is a plan, or guidelines used in the marking of school children's or students' written work by teaching staff.
