Answer:
Shrunken, immensely old.
Step-by-step explanation:
Imagery illustrates a figurative language that employs the words or ideas in such a manner that it pleases our senses. It is visual representation employed to assist the readers to feel the emotion that the writer intends to relate to them as it creates mental images of those objects or ideas in their minds. However, sometimes the writers exaggerate the ideas in order to emphasize a particular message that adds to the complexity. Yet it adds to the beauty of the content like in the given excerpt, the imagery is represented by "shrunken, immensely old" as it displays the image of an old man and his shrunken limbs and skin. The image aids to imagine an old man and provides that feel to relate. Thus, the third one is the answer.
