The correct option is D Siliqua
Silique or siliqua is a fruit of 2 fused carpels with the length being more than three times the width. When the length is less than three times the width of the dried fruit it is referred to as a silicle. The outer walls of the ovary usually separate when ripe, leaving a persistent partition called as replum. This classification includes many members of the Crucifereae family, but some species have a shorter fruit of similar structure, in which case the fruit is called as silicle. Some species that are closely related to plants with true siliques have fruits with a similar structure that do not open when ripe; these are usually called as indehiscent siliques.
Therefore, the correct answer is option D.
