Solution

The correct option is B Latrose
There are modes of dehiscence of the anthers found in the case of angiospermic flowers. Latrose is the form of dehiscence which is in the lateral direction. The anthers break and the pollen grains are liberated away from the center of the flower. There is a movement of the pollen grains towards the lateral sides of the flower. This type of dehiscence is observed in the plants of the family Orchidaceae.
Thus, the correct answer is option D.
