Correct Answer - Option 3 : 2, 3, 6, 5, 1, 4
The logic followed is:
The meaningful order is according to the stages of growth of the plants:
During the first stage of development:
Plants start their lives as seeds and seed germination is an important phase of a plant's life. Inside a seed is an embryo, which is a tiny plant. The outside of the seed has a seed coat, which protects the embryo from injury or drying out.
In the second stage:
Germination is a stage where the plant grows from a seed. All seeds need moisture, oxygen and right temperature to germinate, or grow.
In the third stage:
Nitrogen is a key component of chlorophyll, the green pigment in plants, so it's the critical nutrient when their energy is focused on growing stalks and foliage.
In the fourth stage:
Phosphorus is in extra high demand at the start of a plant's reproductive cycle, the transition from growing leaves to form buds.
In the fifth stage:
Potassium plays a primary role in producing and transporting the sugars and starches plants use up as they develop healthy flowers.
And the last stage is the ripening of the fruits.
So the correct logical order is:
2. Seed
3. Plant
6. Tree
5. Branches
1. Flower
4. Fruits
Hence, the correct answer is "2, 3, 6, 5, 1, 4".
