The answer is A. Herb.
An herb is a plant that is used for its medicinal, culinary, or aromatic properties. Herbs are typically annual or perennial plants that have soft stems and small, simple leaves. They are often used in cooking to add flavor to food, and they are also used in herbal medicine to treat a variety of ailments.
A flower is the reproductive organ of a flowering plant. It is typically composed of four main parts: the sepals, petals, stamens, and pistil. The sepals are the outermost part of the flower and protect the petals while they are developing. The petals are the colorful part of the flower and attract pollinators, such as bees and butterflies. The stamens are the male reproductive organs of the flower and produce pollen. The pistil is the female reproductive organ of the flower and contains the ovary, which produces seeds.
A tree is a large, woody plant that has a single main stem, or trunk, and branches that grow from the trunk. Trees typically live for many years, and some trees can live for hundreds or even thousands of years. Trees are an important part of the environment, and they provide many benefits to humans, such as oxygen, food, and shelter.
A shrub is a woody plant that is smaller than a tree. Shrubs typically have multiple stems that grow from the base of the plant. Shrubs are often used in landscaping, and they can be used to create hedges, borders, and screens.
In the question, “Choose the word which is different from the rest,” the word that is different is A. Herb. Herbs are plants that are used for their medicinal, culinary, or aromatic properties. Flowers, trees, and shrubs are all plants, but they are not used for the same purposes as herbs. Flowers are used to attract pollinators, trees are used for their wood and shade, and shrubs are used in landscaping.
