The most stressful parts of your speech, and the most critical when it comes to good delivery is the
a.
beginning and ending
c.
jokes
b.
body
d.
none of these

Body,  which is C

Cause the beginning is the beginning  of what you write , like this

"Dear grandmother, " or  " This year was a happy year of them of all! "

That is one of the easiest to remember or to script on paper to speak to others

The end is the end of what you already knew you wrote , like this

"Sincerely, Sarah  or " And I could of not think of any year better since this one "

The body Is the biggest of them all cause you have to give all of these ideas, facts, and opinions about a topic ...

so the answer is C " body"

hoped this helped

good question. i'll be looking into that. (this is a joke sir)
