libcamera-still -t 5000 -o test.jpg

AThrows an error because -t is not a valid option

BCaptures an image after 5 seconds delay and saves as test.jpg

CImmediately captures an image and saves as test.jpg

DStarts a 5-second video recording saved as test.jpg

Step-by-Step Solution

Solution:

Step 1: Understand the -t option in libcamera-still
The '-t' option specifies the preview time in milliseconds before capturing the image.
Step 2: Calculate the delay and output behavior
5000 milliseconds equals 5 seconds, so the command waits 5 seconds before taking the photo and saving it as test.jpg.
Final Answer:
Captures an image after 5 seconds delay and saves as test.jpg -> Option B
Quick Check:
-t 5000 means 5 seconds delay before capture [OK]

Quick Trick: -t sets delay in ms before capture with libcamera-still [OK]
