Option 1: Wind - This option refers to the dispersal of seeds by the wind. Wind is a common agent of seed dispersal for many plant species. Seeds that are lightweight and have structures that aid in air travel, such as wings or hairs, can be carried away by the wind to new locations where they can germinate and grow.

Option 2: Fungus - This option states that fungus is not a contributor to seed dispersal. Fungi typically do not have an active role in dispersing seeds. Instead, they primarily decompose organic matter and assist in the recycling of nutrients in ecosystems.

Option 3: Animal - This option suggests that animals play a role in seed dispersal. Many animals, such as birds, mammals, and reptiles, can consume fruits along with their seeds. These seeds are later dispersed through the animal`s digestive system, often in a location far from the parent plant, providing an opportunity for germination and plant propagation.

Option 4: Water - This option refers to seed dispersal through water. Seeds that are buoyant or have structures that enable them to float can be carried by water currents to new areas where they can establish and grow.
