## **Core Concept**
The question tests knowledge of corticosteroids used in respiratory conditions, specifically those administered via inhalation. Inhaled corticosteroids are a cornerstone in the management of asthma and chronic obstructive pulmonary disease (COPD). They work locally in the lungs to reduce inflammation.

## **Why the Correct Answer is Right**
The correct answer, **Beclomethasone**, is a synthetic corticosteroid that is widely used in the treatment of asthma and COPD. It is administered via inhalation, which allows for direct delivery to the lungs, thereby reducing systemic side effects. Beclomethasone works by binding to glucocorticoid receptors in the lung tissue, which leads to the suppression of inflammatory genes and a decrease in the production of pro-inflammatory cytokines.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is blank and does not provide a valid choice for consideration.
- **Option B:** Although **Prednisolone** is a corticosteroid, it is primarily used for its systemic effects and is not typically administered via inhalation for respiratory conditions.
- **Option C:** This option is blank and does not provide a valid choice for consideration.
- **Option D:** This option is blank and does not provide a valid choice for consideration.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that inhaled corticosteroids like **beclomethasone** are preferred in the long-term management of asthma and some cases of COPD because they provide effective anti-inflammatory control with minimal systemic side effects when used at recommended doses.
