A good that is considered to be inferior to a consumer, may be observed as normal good to the another consumer. This is due to _______.

Income of the consumer

The correct answer is option (2) : Income of the consumer

• A good is considered inferior or normal depending on the income level of the consumer.
• Inferior goods are those whose demand decreases as income increases because consumers shift to better alternatives. However, for a lower-income consumer, the same good might still be a preferred choice.
• Normal goods are those whose demand increases as income increases.
