Answer:
Image number 3
Step-by-step explanation:
The sentence is describing image number 3. We can see this is that on this image we have an old castle with turrets, and its surroundings are greenery. This type of castles were built as fortresses as well, which is why they had turrets. The purpose of the turrets was to defend the castle, or rather to be high point places from which the defenses of the castle can easily see and target the enemy that would try to take the castle over.
