Horsetails are described as:

Horsetails are described as:

• A. Primitive perennial that reproduces by creeping roots and tubers.
• B. Annual weed with fibrous roots
• C. Evergreens with needles
• D. Herbaceous with parallel venation.

Answer: (A)

Horsetails are ancient vascular plants that live as perennials, meaning they persist for many years. They spread mainly through underground stems called rhizomes that creep and can bear tubers, which store nutrients and help new growth. This combination of long-term persistence and vegetative spread by creeping rhizomes and tubers is the defining idea behind describing them as primitive perennials that reproduce by these structures. They do produce spores for sexual reproduction, but the vegetative spreading habit is a key feature that makes this description the best fit. They aren’t annual weeds, they aren’t evergreen with needles, and their leaves aren’t arranged as ordinary monocot parallel-veined foliage, so the description that emphasizes creeping rhizomes and tubers best captures their growth habit.
