With the help of a model of the earth and a lamp which of the following concepts can be taught :
(A) Day and night
(B) Climate change
(C) Formation of conventional wind
(D) Water cycle
(E) Change of season
Choose the correct option

Correct option is C

The correct option is (c) Only (A) and (E).
With the help of a model of Earth and a lamp, you can teach the concepts of:
Day and night: By shining the lamp on one side of the Earth model, you can demonstrate how the Earth's rotation causes different parts of the planet to experience day and night.
Change of seasons: By tilting the Earth model on its axis and rotating it around the lamp, you can demonstrate how the tilt of the Earth's axis causes the seasons to change.
The concepts of climate change and formation of conventional wind cannot be taught effectively with only a model of Earth and a lamp. Climate change is a complex phenomenon that is caused by a variety of factors, and a model of Earth and a lamp would not be able to adequately represent all of these factors. Formation of conventional wind requires an understanding of atmospheric pressure and wind patterns, which cannot be demonstrated with a simple model of Earth and a lamp.
The water cycle can be taught to some extent with a model of Earth and a lamp. By shining the lamp on a container of water, you can evaporate some of the water, which will then condense and form clouds. However, this would not be a complete representation of the water cycle, as it would not show how water is transported around the Earth by wind and precipitation.
