Which of the following best describes a change in quantity demanded and a change in demand?

Choose 1 answer:
(A) Both $\Delta Q_{d}$ and $\Delta D$ occur when price changes.
(B) $\Delta Q_{d}$ is a movement along a curve and $\Delta D$ is a movement of the entire curve.
(c) The two terms can be used interchangeably.
(D) $\Delta D$ and $\Delta Q d$ both change in response to income, expectations, preferences, number of buyers, and prices of other goods.
(E) $\Delta D$ occurs when the cost of inputs to production increase, $\Delta Q_{d}$ occurs when the cost of inputs to production decrease

∻Solution∻ ‖ a ⋮ Change in Quantity Demanded: A change in quantity demanded ($\Delta Q_{d}$) refers to a movement along the demand curve due to a change in the price of the good itself. ‖‖ b ⋮ Change in Demand: A change in demand ($\Delta D$) refers to a shift of the entire demand curve, which occurs due to factors other than the price of the good, such as changes in income, preferences, expectations, number of buyers, and prices of related goods. ‖ ∻Answer∻ ⚹ (B) $\Delta Q_{d}$ is a movement along a curve and $\Delta D$ is a movement of the entire curve. ⚹ ∻Key Concept∻ ⚹ Change in Quantity Demanded vs. Change in Demand ⚹ ∻Explanation∻ ⚹ A change in quantity demanded is caused by a change in the price of the good and results in movement along the demand curve. In contrast, a change in demand is caused by factors other than the price of the good and results in a shift of the entire demand curve. ⚹◊What factors can cause a shift in the demand curve according to the information provided?⍭ Generate me a similar question◊
