**Core Concept**
Morphine is a potent opioid analgesic used for pain relief, but it's not typically used for induction of anesthesia in children due to its slow onset of action and potential for respiratory depression. Induction agents for anesthesia in children require rapid onset and safe airway management.

**Why the Correct Answer is Right**
Morphine is an opioid agonist that works by binding to mu-opioid receptors in the central nervous system, producing analgesia and sedation. However, its onset of action is slower compared to inhalational anesthetics, making it unsuitable for rapid induction of anesthesia in children. Additionally, morphine can cause significant respiratory depression, which is a concern during anesthesia induction.

**Why Each Wrong Option is Incorrect**
**Option A:** Halothane is a halogenated inhalational anesthetic agent commonly used for induction and maintenance of anesthesia in children due to its non-irritating properties and rapid onset of action.
**Option B:** Sevoflurane (corrected from Servoflurane) is another popular inhalational anesthetic agent used for induction and maintenance of anesthesia in children, known for its sweet odor and non-irritating properties.
**Option D:** Nitrous oxide is a rapidly acting inhalational anesthetic agent often used in combination with other agents for induction and maintenance of anesthesia in children, providing analgesia and sedation.

**Clinical Pearl / High-Yield Fact**
When selecting an anesthetic agent for induction in children, consider the agent's onset of action, airway safety, and potential for respiratory depression. Always choose agents with rapid onset and minimal respiratory side effects.

**✓ Correct Answer: C. Morphine. Morphine is not used for induction of anesthesia in children.**
