Explanation:

A memoir is usually demonstrated as a literary technique that is employed by authors to reflect or reminisce about the experiences(or factual events) or memories of one's life.

As per the question, the type of details a memoir would include displaying the opinions would be 'the author's commentary' or 'his/her thoughts' as a memoir is meant to relate a specific idea or concern and not the elaboration of events(like biography or autobiography) but rather reminiscing a particular idea or theme. Since the author intends to show opinions thus, it would include the author's commentary as it would assist the audience to have an insight into his perceptions and the thoughts of the author which are reminiscent of the belief system of a person. Thus, option A is the correct answer.
