Solution
The correct option is B Equisetum
The name horsetail, often used for the entire group, arose because the branched species somewhat resemble a horse's tail. Similarly, the scientific name Equisetum derives from the Latin Equus (horse) + seta (bristle).
Equisetum is a living fossil as it is the only living genus of the entire class Equisetopsida.
Therefore, the correct answer is option C.
