Ans. - Option (3)
> Motorcycle : Battery
- Assuming battery as a fuel, it provides energy for the motorcycle to run. So, it's one particular energy source.
Now let's see the options -
Option (1) - If the relation was like Motorcycle: fuel / energy, then this option would have been correct, since star is a general term. We need a particular one. So this cannot be the correct answer.
Option (2) - Assuming motorcycle cannot run without battery, life shouldn't be able to exist without moon. However, life isn't primarily dependent on the moon's energy / black body radiation. So, this cannot be the correct answer.
Option (3) - Sun is primary energy source for our solar system, and more importantly for life. Also, it's a particular one. So, this can be the correct answer.
Option (4) - Can motorcycle exist without battery ? Of course. Can life exist without earth? That's debatable. So, this approach doesn't lead us to give proper reasoning. However, is life dependant on the earth as a primary and particular energy source, compared to all other options? No. So, this cannot be the correct answer.
