When the price of pears increases, the law of demand states that the **quantity demanded** of pears will decrease, as consumers buy less at a higher price. This is a movement **along** the demand curve, not a shift in the demand curve itself.

- **A** is incorrect because a price increase leads to a decrease, not an increase, in quantity demanded.
- **B** is incorrect because a higher price incentivizes producers to supply **more**, not less (quantity supplied rises).
- **D** is incorrect because "demand" refers to the entire curve, which does not shift solely due to a price change.

The correct answer is **C**, as it directly reflects the inverse relationship between price and quantity demanded.

In microeconomics, the law of demand states that, all else being equal, an increase in the price of a good will lead to a decrease in the quantity demanded of that good. Therefore, when the price of pears increases, we expect the quantity demanded of pears to fall. This makes option C the correct answer.

Option A is incorrect because an increase in price typically leads to a decrease, not an increase, in quantity demanded. Option B is incorrect because an increase in price usually leads to an increase in quantity supplied, not a decrease. Option D is incorrect because demand refers to the entire demand curve, which does not shift just because the price changes; what changes is the quantity demanded along the curve.		 C
