A decline in coffee bean supply would lead to a situation where there are fewer beans available in the market to meet consumer demand. When the supply of a product decreases while demand remains constant or increases, the scarcity of the product typically drives the price up. This principle is grounded in basic economic theory, specifically the law of supply and demand. As consumers compete for the limited supply of coffee beans, sellers can charge higher prices, leading to an overall increase in the market price of coffee.

The other options imply either a reduction in price or stability, which contradicts the economic principles at play during a supply decrease. Hence, the correct answer accurately reflects the expected outcome of decreased supply on price.
