The fruit in Datura isA. Loculicidal capsuleB. Septifragal capsuleC. Septicidal capsuleD. Porous capsule

The correct answer is C. Septicidal capsule.

Explanation:
The fruit of Datura is a capsule, a dry fruit that splits open when mature to release seeds.
Specifically, it is a septicidal capsule, meaning that it splits along the septa (the partitions between the locules of the ovary) to release the seeds.
In contrast:
A loculicidal capsule splits along the middle of each locule.
A septifragal capsule breaks away from the septa, leaving the septa intact.
A porous capsule releases seeds through small pores (e.g., in poppy fruits).
Datura shows septicidal dehiscence, which is characteristic of its fruit type.
