Statement A: Natural things can be living or non-living.

Statement B: Living things can be natural.

The correct option is Both the statements are true.

Let us analyze each statement step-by-step to understand why they are both correct:
1. Statement A: Natural things can be living or non-living.
Natural things are those that exist in nature and are not made by humans. In nature, we find two main types of entities:
- Living natural things, such as plants, animals, and birds, which grow, breathe, and reproduce.
- Non-living natural things, such as water, rocks, soil, air, and the sun, which do not have life.
Since natural things encompass both of these categories, Statement A is true.

2. Statement B: Living things can be natural.
All living things that we know of (plants, animals, fungi, bacteria, and humans) occur naturally on Earth. They are not human-made or artificial. Therefore, living things are indeed natural, making Statement B true.

Since both Statement A and Statement B are correct, the statement "Both the statements are true" is the correct option.
