AThrow a JavaScript error because wp.media() is undefined
BUpload a new image automatically without user interaction
CClose any open media uploader popup
DOpen the WordPress media uploader popup allowing single image selection
Step-by-Step Solution
Solution:
Step 1: Understand wp.media() usage
The code creates a media frame with a title and disables multiple selection, then opens the media uploader popup.
Step 2: Analyze each option
Open the WordPress media uploader popup allowing single image selection matches the behavior. Upload a new image automatically without user interaction is wrong because it does not upload automatically. Close any open media uploader popup is incorrect as it opens, not closes. Throw a JavaScript error because wp.media() is undefined would happen only if scripts are not loaded.
Final Answer:
Open the WordPress media uploader popup allowing single image selection -> Option D
Quick Check:
wp.media() + open() = open media popup [OK]
Quick Trick:wp.media() with open() shows media popup [OK]
Common Mistakes:
Assuming it uploads files automatically
Confusing open() with close()
Not enqueuing media scripts causing errors
