As we all know our fav. coconut grows near the sea that's water so definitely it will dispersed by water.
Now let me tell u in detail so that your doubt is crystal clear....
It has some fibres around it they are like brown in colour....
And that always helps it to float and be dispersed by water

PLEASE DNT FORGET TO UPVOTE ME....

Coconut Dispersal by Water:
- Coconuts are adapted to be dispersed by water, which is why they have a unique ability to float.
- The coconut fruit has a tough outer husk that protects the seed inside, allowing it to remain buoyant in water.
- When the coconut falls from the tree and lands in a body of water, such as a river, lake, or ocean, it can be carried away by currents and waves.
- The water dispersal method helps coconuts reach new locations far away from their parent plant, increasing their chances of finding suitable conditions for germination and growth.
Advantages of Dispersal by Water:
- Water dispersal allows coconuts to reach remote islands or coastal areas where other dispersal methods might not be effective.
- Coconuts can travel long distances over water, increasing the chances of colonization in new habitats.
- Water dispersal also protects the coconut from potential predators or competitors that may be present near the parent plant.
Other Dispersal Methods:
- While water dispersal is the most common method for coconuts, they can also be dispersed by other means.
- Wind dispersal is not a significant method for coconuts as their large size and weight make them less likely to be carried by wind.
- Explosive/splitting action is not a common dispersal method for coconuts, as they do not have mechanisms to forcibly eject their seeds.
- Animals can play a role in dispersing coconuts, primarily through consumption and subsequent defecation. However, this method is less common compared to water dispersal.
Therefore, the correct answer is option B: water.
