Correct Answer: Both the assertion and reason are true, and the reason is a correct explanation of the assertion.

Solution : The correct answer is (a) Both the assertion and reason are true, and the reason is a correct explanation of the assertion.

The law of supply states that as the price of a good increases, the quantity supplied of that good also increases, assuming other factors remain constant. This positive relationship between price and quantity supplied is the basis of the law of supply. When the price of a good rises, suppliers have a greater incentive to produce and sell more of that good, leading to an increase in quantity supplied.

Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.

Correct Answer: if the price of a good increases, the quantity demanded of that good decreases

Solution : The correct answer is if the price of a good increases, the quantity demanded of that good decreases.

According to the law of demand, there is an inverse connection between the price of an item and the amount wanted. The rule of demand is based on the assumption that customers have a limited budget and must make decisions about how to spend it. When the price of a product rises, buyers must spend more money to purchase the same amount of the product. As a result of having less money to spend on other things, customers will desire less of the item whose price has soared.

Hence, the second option is correct.

Correct Answer: Marginal utility decreases as consumption increases

Solution : The correct answer is (c) Marginal utility decreases as consumption increases.

According to this law, as a consumer increases the consumption of a particular good or service while keeping the consumption of other goods constant, the additional utility or satisfaction derived from each additional unit of the good will diminish. In other words, the marginal utility of a good tends to decrease as more of it is consumed. This implies that each additional unit of a good provides less additional satisfaction than the previous unit, leading to a downward-sloping marginal utility curve.
