The correct answer is B. Evaluate
Step-by-step explanation:
To grade means to assign a number or letter to a specific work or material such as an essay, piece of homework or presentation. Also, the result of this process is a grade or symbol on a scale. This process is directly related to evaluating because when you assign a grade you asses or evaluate the material considering positive and negative aspects of it and based on this you decide the work is equivalent to a specific grade. For example, when grading an essay you evaluate the structure, arguments, language, among other aspects and if these are good you can assign an 8 or 9 on a scale from 1 to 10. Thus, the word that best fits with grade is "evaluate".
