Negatively sloped demand curves
- A negatively sloped demand curve indicates an inverse relationship between price and quantity demanded.
- As the price of a good or service increases, the quantity demanded decreases, and vice versa.
- This is a typical pattern observed in most markets.

Elasticity of demand
- Elasticity of demand measures the responsiveness of quantity demanded to a change in price.
- It is calculated as the percentage change in quantity demanded divided by the percentage change in price.
- Elastic demand indicates that quantity demanded is highly responsive to price changes, while inelastic demand indicates that quantity demanded is less responsive to price changes.

Intersection of two negatively sloped demand curves
- When two negatively sloped demand curves intersect, it means that the two goods have different price and quantity relationships.
- At the point of intersection, the price and quantity demanded of the two goods are equal.
- Since the two demand curves have different slopes, their elasticities of demand at the point of intersection will also be different.

Elasticity of demand at the point of intersection
- The elasticity of demand at the point of intersection will be the same for both goods.
- This is because the point of intersection represents the equilibrium point where the quantity demanded of both goods is equal.
- At this point, the responsiveness of quantity demanded to a change in price is the same for both goods.
- Therefore, the elasticity of demand at the point of intersection will be the same for both goods, resulting in option 'B' as the correct answer.

Conclusion
- When two negatively sloped demand curves intersect, the elasticity of demand at the point of intersection will be the same.
- This is because the point of intersection represents the equilibrium point where the quantity demanded of both goods is equal.
- The elasticity of demand measures the responsiveness of quantity demanded to a change in price, and at the point of intersection, this responsiveness is the same for both goods.
