Rising food prices can impact food security in Meghalaya by:

Making food less affordable
Increasing farmers' incomes
Reducing food imports
Encouraging food waste

The correct answer is: a) Making food less affordable.

Rising food prices can impact food security in Meghalaya by making food less affordable. This is because when food prices rise, people have to spend more of their income on food, leaving less money for other necessities. This can lead to people going hungry, or eating less nutritious food.

Option b) is incorrect because increasing farmers’ incomes does not necessarily mean that food will be more affordable. Farmers may choose to sell their produce at a higher price, or they may use their increased income to buy other goods and services, rather than passing on the benefits to consumers.

Option c) is incorrect because reducing food imports does not necessarily mean that food will be more affordable. Food imports may be reduced because of government policies, or because of changes in the global market. This does not necessarily mean that food will be more affordable for consumers.

Option d) is incorrect because encouraging food waste does not necessarily mean that food will be more affordable. Food waste may be encouraged by government policies, or by changes in consumer behavior. This does not necessarily mean that food will be more affordable for consumers.
