Verified step by step guidance

Step 1: Begin by identifying the primary function of each body system mentioned in the problem. For example, the digestive system is responsible for breaking down food into nutrients, while the circulatory system transports these nutrients throughout the body.

Step 2: Understand the role of the brain in nutrient delivery. The brain requires glucose and other nutrients to function, which are obtained from food and transported via the bloodstream.

Step 3: Eliminate options that do not directly contribute to nutrient acquisition or delivery. For instance, the skeletal system provides structural support, and the endocrine system regulates hormones, but neither is directly involved in nutrient acquisition or transport.

Step 4: Focus on the digestive system for nutrient breakdown and absorption, and the circulatory system for nutrient transport to the brain. These two systems work together to ensure the brain receives the necessary nutrients.

Step 5: Confirm the correct answer by matching the functions of the digestive and circulatory systems to the requirements of obtaining and delivering nutrients to the brain.
