Sensory language helps a reader to connect with an image or scene, it helps us to feel like we’re there with the character and we’re seeing/hearing/smelling/etc. what they are. For example, ‘Bob could see a mountain’, isn’t particularly sensory, we know there’s a mountain but we don’t know what it looks like, a better sentence would be ‘Bob could see a tall, snow-capped mountain in the distance’ - it gives us details about what Bob can see and so we can picture in our minds. So you need to think about which of the four sentences uses descriptive language like this.
