Answer:
The correct answer is option 2. Practice presenting in front of friend or family
Step-by-step explanation:
Generally while making an oral presentation three things are very vital-
a) Cover all the vital points of the research work presented through oral presentation thus writing all the points on a piece of paper is must.
b) One must use appropriate body gesture while giving the presentation , thus practicing in front of mirror is also a required exercise
c) The presenter must be able to deliver his/her presentation in the stipulated time period thus timing the presentation is also important.
Since mirror practice is sufficient to work on body language, eye contact with the audience and gesture, thus there is no need to practice in-front of friend or family.
