**Core Concept**
The child is presenting with signs of respiratory distress and difficulty feeding, which may indicate a severe respiratory infection. This scenario is a classic presentation of respiratory failure, which requires immediate attention and intervention.

**Why the Correct Answer is Right**
The child's symptoms, including cough, fever, hurried breathing, and high respiratory rate (56/min), suggest a severe respiratory infection. The inability to feed may indicate failure to thrive or respiratory failure, where the child's respiratory system is unable to meet the body's oxygen demands. The management of this scenario would involve providing oxygen therapy, establishing a secure airway, and providing mechanical ventilation if necessary.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not address the child's immediate need for oxygen therapy and airway management.
**Option B:** This option is incorrect because it does not take into account the child's respiratory failure and the need for mechanical ventilation.
**Option C:** This option is incorrect because it does not address the child's high respiratory rate and the need for oxygen therapy.

**Clinical Pearl / High-Yield Fact**
In a child with respiratory distress, always assess for signs of respiratory failure, including inability to feed, high respiratory rate, and failure to thrive. Early recognition and intervention are critical to prevent long-term sequelae.

**Correct Answer: C. Administration of Nebulized Salbutamol and Oxygen Therapy**
