The correct answer is C. Sherry is overwhelmed with buyers of her peaches when she lowers their price by a penny a pound compared to other sellers in the farmers' market.<br /><br />Perfectly elastic demand refers to a situation where a small change in price leads to an infinite change in quantity demanded. In this case, Sherry's peaches have perfectly elastic demand because a small decrease in price (a penny) leads to a significant increase in quantity demanded, overwhelming her with buyers. This indicates that consumers are highly responsive to changes in price, and any decrease in price will result in an infinite increase in quantity demanded.
