Concept:Vivipary germination is a unique process where seeds germinate inside the fruit while still attached to the parent plant, mainly seen in mangroves adapted to saline, swampy conditions.Explanation:In vivipary, the seed does not undergo dormancy. It germinates within the fruit on the parent plant. The embryo pushes out a long, heavy radicle that hangs downwards. Due to increased weight, the seedling detaches from the parent and falls into the soft muddy soil below. This ensures the seedling can anchor quickly in waterlogged, salty environments, avoiding being washed away or drowned. Mangroves (halophytes) grow along seashores and estuaries where conditions are harsh. Examples include Rhizophora and Avicennia. Other plant groups like aquatic plants (hydrophytes), xerophytes, and shrubs do not exhibit vivipary. Aquatic plants germinate in water; xerophytes adapt to dry deserts; shrubs have multiple woody stems but no such germination mechanism.Answer:Mangrove plants (Option C)
