with region please​

Answer 1

Answer:

we need all the above options

Answer 2

Answer:

(c) Be authoritative

Explanation:

You don't need to be authorised to present a presentation, as it is mainly given to you as task, and so obviously you will have to do it... So in my opinion it's (c) , you however need (a) and (b) as they may make people judge you (by your body language).

Mark as brainliest if this satisfies you.
