The AF Form 77, Letter of Evaluation, is designed to allow flexibility in how the information is presented. It can be prepared in either a typed format or handwritten, accommodating various situations and preferences of the individual completing the evaluation.

This broad approach encourages submissions that best reflect the situation of the evaluator, thus making option C the correct and most inclusive choice.
