The correct answer is B. Since slides are sequential, they enable the presenter to always present the intended information.
Step-by-step explanation:
In a slide presentation of any topic, the presenter is required to add only relevant information or elements related to the content such as text, images, videos, etc. Moreover, the presenter must organize this information sequentially, this means every slide should be related to the following and all the slides should be related to the main topic.
Due to this, if the presenter follows the slides during the presentation he/she will only provide relevant information related to the topic or keep "on message" as the slides act as a guide. Also, in cases there is not a slide presentation it is more common for presenters to include irrelevant or disconnected information as they do not follow the sequence provided by slides. Thus, slide presentations help keep the presenter "on message" because "Since slides are sequential, they enable the presenter to always present the intended information".
