Answer: Experiment - randomized block design
Explanation:
A randomized block design (RBD) is an experimental study where the scientist classifies subjects into different groups, denominated blocks. The subjects within each block are assigned to the different treatments, varieties of wheat in this example.
A randomized block design is effective when the subjects within blocks are comparable in how they influence the response variable but differ from other blocks.
