Which description matches Kochia?

• A. Perennial shrub with broad leaves
• B. Annual forb with lance-shaped leaves
• C. Climbing vine with tendrils
• D. Aquatic plant with floating leaves

Answer: (B)

Kochia is described by its growth form and life cycle: it is an annual herb (a forb) that completes its life in one growing season, not a woody shrub. Its leaves are narrow and lance-shaped, rather than broad. This combination—an annual, herbaceous plant with slender, lanceolate leaves—fits Kochia best. It is not a woody perennial shrub, not a climbing vine with tendrils, and not an aquatic plant with floating leaves, which is why those descriptions don’t match Kochia.
