Explanation of Solution
In this question, each block consists of two students starting with the two highest scoring students in the first block, then the next two highest scoring students in the second block and so on. We know these are blocks and not clustersbecause they are set up so that students with similar scores are paired in a block together. We also know they are blocks because the two subjects from each block are then randomly assigned to opposite treatments. Blocks must always be split up proportionally to the number of treatments and be randomly assigned to different treatment groups. Thus, option (b) is correct option that is this is an experiment with blocking.
