The correct answer is the following: <em>option A. Rubrics are often organized into grids.</em> The term "rubrics" is used to define a scoring guide used to communicate and evaluate expectations for a specific assignment by providing feedback on development and grading. They are often organized and presented in the form of a table or grid, to make it clear and easy for teachers and students to understand the information in it. Rubrics are public, which means that they are shared with both the teachers and the students. A writing sample and a writing prompts are two concepts used to guide and help the student to write a piece, but they have nothing to do with the evaluation of the student's work and they are not connected to the rubrics in any way.
