The mother bird lived in a forest with her two newborn babies.

Who lived in a forest?

The correct answer to the question "Who lived in a forest?" is option 'A' - the mother bird.

Explanation:

In order to understand why the mother bird lived in a forest, let's analyze the other options as well:

1. The king: While it is possible for a king to have a palace or a hunting lodge in a forest, it is more common for kings to reside in palaces or castles in cities or towns. Therefore, it is unlikely that the king lived in a forest.

2. Rishi: A rishi, also known as a sage or a hermit, is someone who seeks solitude and often lives in secluded areas like forests or mountains. So, it is possible for a rishi to live in a forest. However, this option is not mentioned in the question, so it cannot be the correct answer.

3. The horse: Horses are not known to live in forests. They are domesticated animals and usually live in stables or pastures. Therefore, it is highly unlikely that a horse lived in a forest.

Conclusion:

Based on the given options, the most likely creature to live in a forest is a bird. Forests provide birds with a natural habitat that offers food, shelter, and protection from predators. Therefore, the mother bird is the correct answer to the question "Who lived in a forest?" (option 'A').
