Question

The disadvantage of which type of speech delivery is that it does NOT sound spontaneous.

Answer 1

The speech which does not sound spontaneous is B Manuscript delivery. 
In a manuscript speech, the speaker reads every word from a pre-written speech. This seems easy enough. 

Answer 2

Answer:

B. Manuscript delivery

Explanation:

Manuscript speaking is the word-for-word iteration of a written message. Which means that the speaker will be focusing their attention in a surface with the words being read (a piece of paper, tablet, or other). This form of delivery is very noticeable and feels like nothing but reproduction of what is in a piece of paper. It is often a very uninteresting way to present something.
