Answer:
4, D, Squinting
Explanation:
I mean you can't gaze at something after sleeping, your eyes are blurry and it would be hard to see. Glancing would mean you were awake, as it is a quick look.
Peering wouldn't work because it's usually when you are hiding or looking at something with difficulty. Peering and squinting makes the most sense, however squinting is the best fitting word.
Hope this helps!
