Which of the forms of energy mentioned below have lastly originated from solar energy?
(i) Bio gas
(ii) C. N. G and L. P. G
(iii) Wind energy
(iv) Geothermal Energy

Options

A. (i), (ii) and (iii)
B. (i), (iii) and (iv)
C. (i), (iii) and (iv)
D. (i), (ii) and (iv)

Explanation

To determine which forms of energy mentioned have originated from solar energy, we will analyze each option:

1. **Bio Gas**:
- Bio gas is produced through the anaerobic digestion of organic matter, such as plant and animal waste. The organic matter itself originates from plants that utilize solar energy for photosynthesis. Therefore, bio gas can be considered to have originated from solar energy.

2. **C.N.G and L.P.G (Compressed Natural Gas and Liquefied Petroleum Gas)**:
- CNG and LPG are derived from fossil fuels, which are formed from the remains of ancient plants and animals that have undergone geological processes over millions of years. These fossil fuels do not directly originate from solar energy; instead, they are a result of ancient biological processes that initially relied on solar energy. Thus, they do not qualify as forms of energy that directly originate from solar energy.

3. **Wind Energy**:
- Wind energy is generated by the movement of air, which is influenced by the uneven heating of the Earth's surface by the sun. The sun's energy causes temperature differences, leading to wind formation. Therefore, wind energy can be classified as originating from solar energy.

4. **Geothermal Energy**:
- Geothermal energy comes from the heat stored within the Earth. While the Earth does receive some heat from the sun, geothermal energy primarily originates from the Earth's internal heat, which is not a direct result of solar energy. Therefore, geothermal energy does not originate from solar energy.

**Conclusion**:
The forms of energy that have lastly originated from solar energy are:
- **Bio Gas**
- **Wind Energy**
