The correct option is 2.
An ephemeral plant is one marked by short life cycles. The word ephemeral means transitory or quickly fading. In regards to plants, it refers to several distinct growth strategies. The first, spring ephemeral, refers to perennial plants that emerge quickly in the spring and die back to their underground parts after a short growth and reproduction phase. Desert ephemerals are plants which are adapted to take advantage of the short wet periods in arid climates. Mud-flat annuals take advantage of short periods of low water. In areas subjected to recurring human disturbance, such as plowing, weedy ephemerals are very short lived plants whose entire life cycle takes less than a growing season. In each case, the species has a life cycle timed to exploit a short period when resources are freely available.
