Correct Option: A. Okra Explanation of Why the Answer is Correct: A capsule is a type of dry fruit that splits open at maturity to release its seeds. Capsules are typically formed from two or more carpels (the female reproductive structures of a flower) and can open in various ways, such as through pores or slits. Okra (Abelmoschus esculentus) is classified as a capsule because:

1. Structure: The fruit of okra is elongated and contains multiple seeds. When it matures, it dries out and splits open along its seams, allowing the seeds to be dispersed. This characteristic splitting is a defining feature of capsules.
2. Development: The okra fruit develops from a flower with multiple carpels, which is typical for capsule fruits. Each carpel can contain one or more seeds, and as the fruit matures, it becomes dry and splits open.

Why the Other Options are Wrong or Weaker: B. Groundnut (Arachis hypogaea): - Groundnut, also known as peanut, is classified as a legume. Legumes are fruits that develop from a single carpel and typically do not split open at maturity. Instead, the groundnut pods remain closed until they are harvested, making them distinctly different from capsules. C. Mango (Mangifera indica): - Mango is classified as a drupe (or stone fruit). Drupes have a fleshy outer layer and a hard inner layer that encases the seed. Unlike capsules, drupes do not split open to release seeds; instead, the fruit is consumed, and the seed is discarded or planted. D. Coconut (Cocos nucifera): - Coconut is classified as a drupe as well, specifically a fibrous drupe. Similar to mangoes, coconuts have a hard shell that protects the seed inside. The outer layer is fibrous, and the seed does not split open like a capsule. Summary of Key Points:

• Capsule: A dry fruit that splits open at maturity to release seeds (e.g., okra).
• Groundnut: A legume that does not split open; it remains closed until harvested.
• Mango and Coconut: Both are drupes, characterized by a fleshy outer layer and a hard inner layer that protects the seed.
• Understanding the classification of fruits is essential for identifying their characteristics and reproductive strategies.

Revision Summary:

• Capsules split open to release seeds; okra is a prime example.
• Groundnuts are legumes and do not split open.
• Mangoes and coconuts are drupes, with hard shells protecting their seeds.
• Familiarity with fruit classifications aids in understanding plant biology and reproduction.
