The correct option is D Cardiospermum
Air dispersal of inflated fruits can be seen in Cardiospermum. Cardiospermum is an example of anemochory which is defined as seed dispersal by wind. Common dispersal syndromes of anemochory are wing structures and brown or dull coloured seeds. Seeds are named for anemochory flyers, rollers or throwers to represent the seed dispersal syndromes and their behaviour. Wind dispersers mature in the dry season for optimum high long-distance dispersal to increase success of germination.
Therefore, the correct answer is option D.
