 We, in our daily lives, use energy from various sources for doing work. We use diesel to run our trains. We use electricity to light our street-lamps. Or we use energy in our muscles to cycle to school. 

• By this standard, children are aware of what constitutes energy, energy is what we used in making food, for travel, etc.
• What we need to do now is to develop their ideas to save energy. We would start by analyzing what we have been using and the energy sources our friends are using.
• Children understand energy better through the activities given in the text.
• They are also expected to make a list of energy sources and what they use and also find out their ingredients and their sources. 
• The child should also investigate whether the sources are conventional or non-conventional. 
• For this, we should ask a student to write slogans on saving energy, Make a model/project to depict energy-saving, and encourage students to save energy in various ways in their lives. Also, ask them to tell their friend about energy saving.

Thus from the above-mentioned points, it is clear that options A, C, and D are correct.
