Solution
The correct option is A Equisetum
Horsetail is in a family of plants containing about 35 species within the genus Equisetum. Scouring rush (Equisetum hyemale) is evergreen, with leafless, hollow, segmented stems with ash-colored bands. Stems grow to about 1/2 inch in diameter and reach up to five feet tall. Because the stems are rough and durable (due to their high silica content), they were called as scouring rushes, because early pioneers used them to scrub pots and pans.
