Answer 1

It is also important to disperse the fruits from one place to another to increase its availability in the surrounding and for maintaining the species in the environment.

Complete answer: The fruit of Tribulus has a various number of sharp and rigid spines on its surface, these spines protect it from different adverse environmental conditions and also from the predator’s but also due to these spines the fruit of Tribulus can not be dispersed by the action of water and wind due to its weight as it not so light weighted so that it can easily float on the surface of water and wind can transfer it from one place to another.
So, the fruit of the Tribulus is dispersed with the help of animals.
As the fruit consists of spines on its surface and animals have a hairy body, a large number of long hairs are present on the body of the animals.
So the spines of the fruit get attached to the hairs of the animal as animals went from one place to another it also disperse the fruit of the Tribulus with itself from one place to another.

So, the correct answer is “Option C ”.

Note: The fruits which can easily float on the surface of the water are dispersed by the water as a medium and the fruit which is lightweight and can be carried out by the wind from one place to another.
