Answer: (D)

Verified step by step guidance

1. Identify the key functions mentioned in the question: integration of emotions, motivation, and memory.
2. Recall that the respiratory system primarily manages breathing and gas exchange, so it is unlikely to be responsible for these psychological functions.
3. Understand that the endocrine system regulates hormones and influences bodily functions but does not directly integrate emotions, motivation, and memory.
4. Recognize that the somatic nervous system controls voluntary muscle movements and sensory information, not emotional or memory processing.
5. Conclude that the limbic system, a complex set of brain structures, is primarily responsible for integrating emotions, motivation, and memory, making it the correct answer.
