The correct answer is A. Introduction
Step-by-step explanation:
A slide presentation is a visual tool that helps speakers during a presentation or speech; due to this, the content included in the slides is organized according to the information the speaker wants to deliver and this often includes an introduction, body, and conclusion.
In the case of the introduction, this refers to the first slide/s that present the topic and main ideas to the audience. This includes informing the audience about the purpose, topic and main points of the presentation. According to this, it is likely the section "Today we will address..." is part of the introduction in a presentation because this only explains to the audience what the presentation is about.
