Hint: Herbs are plants with savory or aromatic properties that are used for flavoring and garnishing food, for medicinal purposes or fragrances; vegetables and other plants consumed for macronutrients are not considered herbs.
Complete answer:
Herbs have a wide range of applications, including culinary, medicinal, and, in some cases, spiritual. The term "herb" is used differently in culinary and medicinal contexts; in medicinal or spiritual contexts, any part of the plant, including leaves, roots, flowers, seeds, root bark, inner bark (and cambium), resin, and pericarp, may be considered "herbs."
Option A: Potato: Potato plants are herbs because as they grow, their compound leaves produce starch, which is then transferred to the tips of their underground stems (or stolons).
Option: B: China rose: It is a shrub with a height of 1–2 m that grows in hedges or thickets. The leaves are pinnate, with 3–5 leaflets that are 2.5–6 cm long and 1–3 cm wide.
Option C: Fir: Fir (genus Abies), a genus of over 40 species of evergreen trees in the Pinaceae family of conifers.
Option D: Date Palm: Date palm (Phoenix dactylifera), Arecaceae palm tree cultivated for its sweet edible fruits. The date palm has been prized since antiquity and is thought to have originated in what is now Iraq.
Thus, Potato is a herb. So, the correct answer is option A: Potato.
Note: Herbal teas can be made by infusing some herbs in boiling water (also termed tisanes). Typically, dried leaves, flowers, or seeds are used, as are fresh herbs. Herbal teas are typically made from aromatic herbs, do not contain tannins or caffeine, and are not mixed with milk. Chamomile tea and mint tea are two common examples. Herbal teas are frequently used as a source of relaxation or can be associated with rituals.
