Hint: A capsule is the most common type of fruit produced by angiospermic plants. It is a dry fruit which splits to release the seeds. The plants which have capsular fruit are Eucalyptus, Mahogany, chestnut, cotton etc.

Complete answer:
To answer this question, we must know about the different types of capsular fruit. A capsule is a simple dry fruit. It has two or more carpels. Locule is referred to as the chamber within the fruit. The locules contain seed. The capule is dehiscent and splits apart to release the seeds.

The different types of capsule are-
Loculicidal- It is a dry dehiscent fruit that opens in the middle of the locule. For example lily.
Septicidal- It is a dry dehiscent fruit that opens longitudinally along the septum. Example is Datura.
Septifragal- It opens by breaking away from the partitions but remains attached to the common axis. Example- Paullinia.

The capsular fruit dehisces through the loculi and exposes the column bearing seeds. The fruit is called septifragal.Thus the answer is septifragal.

Hence the correct answer is option ‘C’

Note: The capsule fruit can be classified based on the number of locules as unilocular, bilocular, trilocular etc. In the capsula fruit, the pericarp rupture after ripening and the seed are exposed to outside. In gymnosperms, the number of locules may be equal or less than that of the carpels. An indehiscent fruit is a dry fruit which does not split open on maturity, Example- grains.
