Fruit M and fruit N are both dry. Fruit M is light and has a papery skin. Fruit N is long and has a slit along its side. How are the seeds of the fruits M and N dispersed?

AM: By wind; N: By animals
BM: By wind; N: By splitting
CM: By splitting; N: By wind
DM: By water; N: By animals


(B) Light weight and papery skin of a fruit are adaptations to float in air from a long time. The seeds along with the fruit get dispersed to long distances by floating in air. Fruit N has a slit along its side. It indicates that the seeds are dispersed by splitting of the fruit along the slit when matured. There is a line where splitting occurs after maturation, exposing the seeds which will fall from the fruit.
