Answer:
The body of the speech should NOT be completely memorized .
Step-by-step explanation:
Not unless one has got abnormal mental abilities , a person cannot memorize the entire body of a speech leave alone being informative or typical to any field ,.
Is it really possible for a person to memorize like 1000 words in the correct order in which they have been written ? The answer is no as this is a huge volume of words .One thousand is just an example as they can be more or less .
The other three points are correct as they are feasible .For instance the body part of a speech contains the main point therefor 'A' is correct .As for 'B' arranging the point in a logical sequence is in order as it implies the reality of the speech and also brings logical sequence and flow of ideas .
Finally 'D' providing transition statements ensures that the speech has a flow of ideas and the audience can connect and relate to the ideas just as the reader or writer understands it .
