Final answer:
The soul needs the body for acquiring knowledge through the senses and for the basic materials that it organizes and gives life to.
Step-by-step explanation:
In Aristotle's understanding, the soul needs the body in several ways. One way is that our intellects acquire knowledge through the senses, which are part of the body. For example, we learn about the world around us by seeing, hearing, and touching. Another way is that the body provides the basic materials that the soul organizes and gives life to. Without a body, there would be no material for the soul to work with. Therefore, the correct answer is option D, which includes both of these reasons.
