• The sun is made up of about 80% hydrogen, 20% helium and only 0.1% other elements. 
• Sun is the most important source of energy. The sun is the source of life on our planet Earth and, directly or indirectly, is the fuel for most renewable systems. Photovoltaic and solar thermal systems, as well as solar thermal power stations, convert solar irradiation directly into useable energy.
• Hence Multinational source of energy is the sun.
• So, the correct answer is 'Sun'.

Sun is the ultimate and major source of energy which is required and fulfills the need of the world. photosynthesis and chemical bonds are performed and formed respectively by the sunlight due to which all the necessary reactions occur leading to the completion of all the processes. Green plants require sunlight to produce organic food in which water and gases mix with sunlight to produce their food.

For all organisms, the sun, or solar radiation, is the ultimate source of energy. Plants are primary producers of energy from the sun. Plants use sun, chlorophyll, water, carbon dioxide and nutrients to manufacture glucose, an alternate form of energy. 

The Rainfall pattern depends on the number of water bodies in an area because which area has more water bodies that area evaporates more water and this evaporation increases the precipitation water cycle and hence initiate  the rainfall 

Birds that nest in the Northern Hemisphere tend to migrate northward in the spring to take advantage of burgeoning insect populations, budding plants and an abundance of resting locations. This is guided by celestial navigation with a sextant.
