The description that BEST matches the systems with their functions is:
The urinary system allows you to eliminate solid waste. The digestive system is responsible for absorption of valuable nutrients. The circulatory system transports important molecules.
This set accurately describes the functions of the urinary system (related to liquid waste, not solid), the digestive system (which absorbs nutrients), and the circulatory system (which transports molecules throughout the body).
However, please note that the statement about the urinary system should correctly refer to liquid waste, since solid waste is primarily related to the digestive system. Therefore, it's important to rephrase that particular aspect for complete accuracy, but in the context of matching systems to their primary functions, this answer stands out.
The other options contain several inaccuracies regarding the functions of the systems mentioned.
