Some seeds are dispersed by animals, especially spiny seeds with hooks which get attached to the bodies of animals and are carried to distant places. Examples is/are:A. Xanthium and urenaB. XanthiumC. UrenaD. Coconut

The correct answer is A. Xanthium and Urena.

Explanation:

Some seeds are adapted to be dispersed by animals, and these seeds often have hooks, spines, or other features that allow them to attach to the fur or skin of animals. This type of seed dispersal is known as zoocory.

Xanthium and Urena are both examples of plants that produce spiny seeds with hooks. These hooks allow the seeds to attach to animals' fur or feathers, and as the animals move around, they carry the seeds to new locations, aiding in seed dispersal.

Coconut, on the other hand, is typically dispersed by water (hydrocory) due to its large, buoyant nature, and does not rely on animals for dispersal.

Therefore, the correct choice is A. Xanthium and Urena.
