Answer:
A). Indicates that more is supplied at higher prices.
Step-by-step explanation:
As per the law of supply, an increase in supply would signify that 'the firms are willing to sell more goods at a higher price' because they can make more profit now as compared to the supply at a lower price. The supply and price of a normal good have a positive association and therefore, an increase in price stimulates the supply as well. However, there are certain other factors responsible for the increase in supply like a fall in costs of production, an increase in the number of producers in the market, etc yet among the given options, the first one asserts a true claim. Thus, option A is the correct answer.
