My cousin stayed awake _____ night trying to think of a catchy slogan.

• A. each
• B. every
• C. the
• D. all

Answer: (D)

The idea here is to pick the phrase that best expresses duration during the night. When you say someone stayed awake all night, you’re emphasizing that the entire night was spent awake, with no sleep. That’s the natural, idiomatic way to describe a single night’s length of wakefulness. The other options would refer to multiple nights (each night, every night) or sound awkward in this context (the night) because they don’t convey the full duration of one night. So the best fit is all night.
