Answer:
C. Supply of lobster is greater in summer than in spring .
Step-by-step explanation:
Demand & supply refer to consumers & producers ability & willingness to buy & sell at given prices respectively .
Demand curve is downward sloping, supply is upward sloping - due to law of demand & law of supply .
Market Equilibrium is where Demand = Supply & the curves intersect . Decrease in demand (Lobsters spring case) generally creates excess supply which leads to competition among sellers and reduces the prices . However if price is increasing despite of demand decrease (Lobsters spring case) , the excess supply due to demand shortage would not have happened due to c) lesser supply in spring. So , decrease in demand off set by decrease in supply also in spring would have led to lobsters' higher price despite of lower demand in spring.
