To insert a hyperlink in a slide

The correct answer is Both a & b. In modern presentation software like Microsoft PowerPoint, Google Slides, and LibreOffice Impress, there are multiple ways to insert a hyperlink into a slide. The two most common methods are exactly those listed in options 1 and 2:

• Option 1 – Choose Insert > Hyperlink: This is the standard menu‑based method. In PowerPoint, you navigate to the Insert tab on the ribbon and click on Hyperlink (or Link). In Google Slides, you use the Insert > Link menu. This opens a dialog box where you can paste a web address, link to another slide, or even create an email link.
• Option 2 – Press Ctrl (shortcut): While the option says simply "Press Ctrl", the actual universal keyboard shortcut is Ctrl + K (or Cmd + K on macOS). This shortcut instantly opens the hyperlink insertion dialog box without navigating through menus, making it a time‑saving alternative. Since the option intends to represent the shortcut method, it is considered valid.

Option 3, "Hyperlinks can’t be inserted in slides," is completely incorrect—slides support hyperlinks to web pages, files, email addresses, and even other slides within the same presentation. Option 4 ("Both a & b") correctly combines the two legitimate insertion methods.

Therefore, the correct choice is "Both a & b" because both the menu command (Insert → Hyperlink) and the keyboard shortcut (Ctrl+K) are standard ways to insert a hyperlink in a slide.
