(A) True
(B) False

Hint:Solar energy is a light and heat energy that comes from sun. There are many ways of harnessing this energy as it is a good source of renewable energy. One such example, where solar energy is used in a solar dryer, is a device that uses solar energy to dry food and can be used for food preservation for a longer duration of time.

Complete step by step answer:
We have been given a statement i.e., “In solar dryers, we can keep dried fruits for a longer period of time.” We need to state whether it is true or false. We know that, solar dryer is a device that uses solar energy to dry food. It is one of the ancient methods of drying foods, and it is used to preserve food for a longer period of time. In this, the first step is to dry the food in the sun, or in a food dehydrator, then a solar dryer is used to preserve this food. And the food remains in good quality and can be consumed later. Hence, in a solar dryer, we can keep dried fruits for a longer period of time. Hence,the statement is true.

Note: Nowadays, many solar devices are used in our day to day life. Because it is good to lessen the carbon footprint as solar energy is a clean and renewable source. So, it is good for our ecosystem, as it doesn’t create any kind of pollution.
