Answer :

To determine the correct Speed Key sequence for switching a presentation to Reading view in PowerPoint, let's analyze the options provided:

1. Option a) ALT, W, M
2. Option b) ALT, W, I
3. Option c) ALT, W, L
4. Option d) ALT, W, D

In PowerPoint, to switch to Reading view, the Speed Key sequence involves accessing the "View" tab and then selecting the "Reading View" option. Here's how you can deduce the correct sequence:

1. Pressing `ALT` will activate the Quick Access Toolbar and display shortcut keys for the ribbon tabs.
2. Pressing `W` will navigate to the "View" tab.
3. Within the "View" tab, we need the shortcut for "Reading View."

After navigating to the "View" tab with `ALT` and `W`, the shortcut for "Reading View" can be determined:

- `ALT, W, M` is not the shortcut for Reading View.
- `ALT, W, I` is not the shortcut for Reading View.
- `ALT, W, L` is not the shortcut for Reading View.
- `ALT, W, D` is the correct sequence for Reading View.

Therefore, the sequence you would press to switch a presentation to Reading view is:

d) ALT, W, D
