Explanation:

Petrol, wax, and kerosene are all forms of fuel, while juices are not. Hence, the odd one out is option C - Juices.

1. Petrol:
- Petrol is a flammable liquid that is derived from crude oil.
- It is commonly used as a fuel for automobiles and other machinery.
- Petrol is highly combustible and is primarily used in internal combustion engines.

2. Wax:
- Wax is a solid material that is usually derived from petroleum.
- It has a high melting point and is often used in making candles, wax seals, and as a coating for various purposes.
- Wax can also be used as a fuel in certain situations, such as for heating or as a component in wax-based fuels.

3. Kerosene:
- Kerosene is a flammable hydrocarbon liquid that is commonly used as a fuel for heating and lighting.
- It is derived from petroleum and has a lower energy density compared to petrol.
- Kerosene is often used in lamps and stoves, especially in areas where electricity is not readily available.

4. Juices:
- Juices are liquids extracted from fruits or vegetables.
- They are typically consumed for their nutritional value and taste.
- Juices do not serve as a fuel source and are not used for combustion or energy production.

In conclusion, while petrol, wax, and kerosene are all forms of fuel, juices do not fall into this category.

On the basis of solubility,juice becomes the odd one

but on the basis of states of matter,wax is odd one because all others are liquids

so please specify on which basis odd ones has to be chosen.
