The correct answer is D. House.
Price elasticity of demand is a measure of how much the quantity demanded of a good or service changes in response to a change in its price. It is calculated by dividing the percentage change in quantity demanded by the percentage change in price.
Goods with inelastic demand have a low price elasticity of demand, meaning that a change in price will have a small effect on the quantity demanded. This is because these goods are essential or difficult to substitute. For example, people need a place to live, so they are unlikely to stop buying a house even if the price goes up.
Goods with elastic demand have a high price elasticity of demand, meaning that a change in price will have a large effect on the quantity demanded. This is because these goods are not essential and there are many substitutes available. For example, people may choose to drink less tea if the price goes up, because there are many other beverages available.
In conclusion, the good with the least price elasticity of demand is a house. This is because houses are essential and there are few substitutes available.
