The correct option is B. Price of the good falls; expenditure on it remains unchanged.
Demand for a good is termed inelastic through the expenditure approach when the price of the good falls, and expenditure on it remains unchanged. In other words, a fall in price leads to only a small increase in quantity demanded, resulting in overall expenditure remaining relatively constant.
