Option 3 : 1, 2 and 4 only

The correct answer is 1, 2 and 4 only.

Bioethanol - or simply 'ethanol' is renewable energy the source made by fermenting the sugar and starch components of plant by-products - mainly sugarcane and crops like grain, using yeast. Hence statement 1 is correct.
It is also made from corn, potatoes, milk, rice, beetroot and recently grapes, banana and dates depending on the countries agricultural strength. Hence statement 3 is not correct.
Bioethanol has many uses:
- It is blended with petrol to make a truly sustainable transport fuel, it's used in cosmetic and other manufacturing processes, and it creates a clean burning flame even for house uses. Hence statement 2 is correct.
Bioethanol fuel is completely composed of biological products.
- The combustion of bio ethanol results in a clean emission: Heat, Steam and Carbon Dioxide. Hence statement 4 is correct.
- Carbon dioxide is absorbed by plants. It is then processed via photosynthesis to help the plant grow.
- This infinite cycle of creation and combustion of energy makes bio ethanol a carbon neutral fuel source.
