Solution(By Examveda Team)

The annual flower used as a live screen is the sweet pea.
Annuals are nature’s powerhouse plants, marching through a single growing season with sure and steady colour. The term "annual" when applied to herbaceous ornamentals refers to plants that are grown for only one season.
Rapid-growing annual plants are suitable for large screens and hedges when trained on fences and trellises.
