Which one of the following statements is not correct?

The statement that Mangifera indica is the national animal of India is incorrect. Mangifera indica is actually the botanical name for the mango, which is the national fruit of India [1]. The national animal of India is the Royal Bengal Tiger (Panthera tigris tigris), chosen for its strength, grace, and agility [1]. Other statements are accurate: Pavo cristatus (Indian peacock) was declared the national bird in 1963 due to its cultural and religious significance [1]. Nelumbo nucifera Gaertn (Lotus) is the national flower, symbolizing spirituality and purity [1]. Ficus benghalensis (Banyan tree) is the national tree, representing longevity with its vast canopy and aerial roots [1]. These symbols were selected to reflect India's rich natural heritage and unique identity.
