Solution

The correct option is B Ramenta
The leaves of Fern are also known as fronds. The frond of fern is a pinnately compound leaf and has its origin in a small outgrowth on the stem near its growing point. The petiole of the leaf ends in a long rachis, which bears pinnae. In young leaves, both the rachis and petiole are covered with small, brown hairy scales, called as ramenta. The young leaves are circinate, and they uncoil like a watch spring as they grow. The mature leaves last only for one season and again ten to twenty leaves come out, which remain spirally arranged on the rhizome.
