Option 1 -> Incorrect, as the passage shows he was actually impressed by discovering the morning's beauty ("I realised what I had been missing").
Option 2 -> Incorrect, this is the opposite meaning - the mild sunshine and fresh air were described as "new to me."
Option 3 -> The phrase "never been a morning person" is an idiom meaning someone not accustomed to waking up early or being active in the mornings, which fits the context perfectly.
Option 4 -> Incorrect, as the morning was peaceful and serene, not hustling and bustling; plus "morning person" refers to habit, not preference for activity levels.
Hence, Option 3 -> The idiom "never been a morning person" means someone who isn't in the habit of waking up early or engaging in morning activities, which is supported by the fresh air being "new" to him and his realization of what he had been missing -> correct
