Answer 1

Hint:
Perennial plants are plants that complete their life cycle in more than two years. Their cycle of life continues for a longer period of time, once they grow, they start to bear flowers, produce fruits, and seeds.

Complete answer:
Perennial plants are plants having a life cycle that is more than two years. Once the bearing starts, these produce seeds or flowers every year. They do not require replanting. These Perennials are, usually, categorised into two groups: Woody perennials and herbaceous perennials. Alongside a couple of bushes, trees are totally arranged into perennials. For example, banana, banyan, coconut, tomatoes, ginger, mango, palm, etc.
From seed germination to seed production, the plants which complete their life cycle in one growing season are called ‘annuals’. They complete their life cycle - seed germination, growth, flowering, seed formation and die in one growing season or year. They are commonly called ‘seasonal’ as they require replanting every season and are mostly grown through seeds. Wheat, corn, mustard, watermelon, lettuce, jowar, bajra, sunflower are a few examples of annual plants.
Thus, Banyan is the odd one out since it is the only perennial plant in all these plants while the rest of them are annual plants.

Note:
Biennials are plants that complete their seed-to-seed life cycle in two seasons or years. Most of the temperate seasonals are biennial in nature since they complete vegetative growth in one season or year and flowering to seed formation in another season or year. These require replanting. A few herbs are also classified as biennials, including spinach. Along with spinach and other herbs, biennials also include onions, carrots, petunias, radish, cabbage, etc.
