Explanation:
To delete an embedded object, you need to follow these steps:

1. Select the object:
Click on the embedded object that you want to delete. This will highlight the object and indicate that it is selected.

2. Press the Delete key:
After selecting the object, press the Delete key on your keyboard. This will remove the object from the document.

Why option 'D' is the correct answer:
Option 'D' states that you should select the object and then press the Delete key. This is the correct method to delete an embedded object in most software applications, including word processors and presentation software.

Selecting the object before deleting ensures that you are deleting the intended object and not accidentally deleting other content in the document.

Pressing the Delete key removes the selected object completely from the document. This action cannot be undone, so make sure you have selected the correct object before deleting it.

Alternative methods:
While option 'D' is the most common method, there may be alternative ways to delete embedded objects depending on the software you are using. Some other possible methods include:

1. Right-click and choose Delete:
In some applications, you can right-click on the object and choose the "Delete" option from the context menu. This will also remove the object from the document.

2. Use the Edit menu:
In certain software, you may find a "Delete" option in the Edit menu. Selecting this option will delete the currently selected object.

Conclusion:
To delete an embedded object, the correct method is to select the object and then press the Delete key. This ensures that you delete the intended object without accidentally deleting other content in the document. However, alternative methods such as right-clicking and choosing Delete or using the Edit menu may also be available in some software applications.
