Solution
The correct option is B Roll up during drought
Under dry conditions, the xerophytic species of Selaginella roll into brown balls but remain uprooted. This phenomenon is called as a cespitose habit. But during moist conditions, the brown balls become green and unroll again. Therefore, these plants are called as resurrection plants. e.g. Selaginella lepidophylla and Selaginella bryopteris.
