In what forms can Mildew primarily be found?

Mildew primarily exists in inanimate objects and plants, making this the correct choice. Mildew is a type of fungus that thrives in damp, warm environments and can often be seen on the surfaces of various materials such as wood, paper, and fabrics. Additionally, mildew can grow on plants, particularly when they are overwatered or exposed to high humidity. This adaptability allows it to proliferate in different settings where moisture is present.

The other options do not accurately reflect the characteristics of mildew. While it is true that mildew can affect food products due to spoilage, stating it exists only in food products limits its broader presence. Also, mildew is not confined to humans alone, as it occurs outside of human environments in nature and on surfaces. Lastly, limiting mildew to only being found in water inaccurately represents its habitats; while moisture is a critical factor for its growth, mildew can develop on multiple surfaces and not solely within water.
