**Core Concept**
Inhalational anesthetics are volatile liquids that produce general anesthesia when inhaled. In pediatric anesthesia, the choice of agent depends on factors such as age, weight, and desired rapidity of induction. The ideal agent for children should have a low solubility in blood to allow for rapid induction and recovery.

**Why the Correct Answer is Right**
Sevoflurane is the preferred inhalational anesthetic agent in children due to its non-irritating properties, low solubility in blood, and rapid onset and recovery. It has a sweet, non-pungent odor that minimizes airway irritation and makes it ideal for inhalational induction in pediatric patients. Sevoflurane also undergoes minimal metabolism, reducing the risk of hepatotoxicity.

**Why Each Wrong Option is Incorrect**
**Option A:** Isoflurane has a pungent odor and can cause airway irritation, making it less suitable for inhalational induction in children.
**Option B:** Halothane is associated with hepatotoxicity, particularly in children, due to its high metabolism, which makes it a less desirable choice.
**Option C:** Desflurane has a pungent odor and can cause airway irritation, similar to isoflurane, making it less suitable for inhalational induction in pediatric patients.

**Clinical Pearl / High-Yield Fact**
Sevoflurane is often used for inhalational induction in children due to its non-irritating properties, but it can cause a decrease in blood pressure due to vasodilation. This effect is more pronounced in children than adults.

**Correct Answer: C. Sevoflurane**
