Short cut Ctrl + H is used to

Ctrl + H is a shortcut in Microsoft Word.
It's used to quickly access the "Find and Replace" feature.
When you press Ctrl + H, a dialog box pops up.
This dialog box has two main tabs: "Find" and "Replace".
The Ctrl + H shortcut directly opens this dialog box with the "Replace" tab already selected and active.
So, you can immediately start replacing text in your document without having to click on the "Replace" tab first.
The other options are incorrect because:
Option B, C & D: are related to "Insert Hyperlink", which has a different shortcut key.
