Explanation:

Delivering a speech or giving a presentation for most people is one of the most difficult tasks as multiple factors need to be considered including the audience, the use of language, the purpose of the speech, the organization of the content, etc. Additionally, of all the aspects previously mentioned vary in every situation, which means each speech should be unique and respond to the context and situation of it. Because of this, using the speech of someone else instead of delivering the speech according to the factors previously mentioned might have different negative effects.

In the case of Walter delivering President Kenedy's speech he might find the audience will not understand his purpose and the language he is using as Presidential speeches use different language to other speeches and languages and speeches have changed since Kennedy gave speeches (the 1960s); also, the audience will notice this and realize it is not Walter's speech which means they will know he is not being authentic and because of this the audience will not be engaged to the speech or pay attention to the words of Walter which will make the speech a complete failure. Thus, in the case presented Waler is unlikely to succeed because the audience will feel he is unsincere, they will not understand why he is speaking oddly and will lack engagement with his speech or all of the above (Option D).
