Explanation:

Plants have different ways of dispersing their seeds and one of the most common ways is through air or wind. Seeds that are dispersed by air or wind have certain adaptations that help them to be carried by the wind. The options given in the question are all adaptations that seeds can have to be dispersed by air or wind. The correct option is c) Hair or wings.

Seeds dispersed by air/wind:

Seeds that are dispersed by air or wind have to be lightweight and have adaptations that allow them to be carried by the wind. Some of the common adaptations of seeds that are dispersed by air or wind are:

- Hair or wings: Seeds that have hair or wings are able to float on the wind. Examples of seeds that have hair or wings are dandelion, maple, and ash.

- Sticky, hooks or spikes: Seeds that have hooks or spikes can attach themselves to animals or clothing and be carried to new locations. Examples of seeds that have hooks or spikes are burdock, cocklebur, and burr clover.

- Spongy: Some seeds have a spongy texture that allows them to float on the water. Examples of seeds that have a spongy texture are water lily and water hyacinth.

Conclusion:

Seeds that are dispersed by air or wind have adaptations that help them to be carried by the wind. The correct option in the question is c) Hair or wings, which is one of the common adaptations of seeds that are dispersed by air or wind.
