B) the science of classification of organisms.

To select three main parts of vascular plants, let's look at the given options and identify the main parts:

1. Flowers: Flowers are reproductive structures in vascular plants, used for the production of seeds. However, not all vascular plants have flowers.

2. Leaves: Leaves are one of the primary structures of vascular plants. They are responsible for photosynthesis, the process by which plants convert sunlight into energy.

3. Roots: Roots are integral parts of vascular plants. They anchor the plant into the ground and absorb water and nutrients from the soil.

4. Seeds: Seeds are reproductive structures formed in the flowers of some vascular plants. They contain the embryo, which can later germinate and grow into a new plant.

5. Stems: Stems are another main part of vascular plants. They provide support to the plant and transport water, nutrients, and sugars between the roots and leaves.

From the given options, the three main parts of vascular plants are: leaves, roots, and stems.
