D Correct answer
Explanation

It is a simple, dry, dehiscent fruit developing from the bicarpellary, monolocular ovary having two parietal placentae. The ovary is monolocular in the beginning, but becomes bilocular due to the development of a false septum called replum. The pericarp dehisces into two halves from below upwards. The seeds remain attached to the central replum, e.g. mustard, radish, etc.
