Sensory detail is when an Author uses the five senses to help add descriptive language to their work. So you simply ask yourself, which uses the most descriptive language?
The correct answer is C) The skilled photographer shot a massive oak tree, using the scarlet sunset as an incredible background.
Sensory details are such details that appeal to your senses. They create imagery in a text, use descriptive words to create powerful images, so detailed that a reader can vividly imagine the picture before his or her very own eyes. This is what happens in sentence C - the descriptions are very detailed because they use the most sensory details.
