Verified step by step guidance

1. Understand the concept of symbiotic relationships: Symbiosis refers to the interaction between two different organisms living in close physical association, typically to the advantage of both or one of the organisms.
2. Identify the types of symbiotic relationships: There are several types of symbiotic relationships, including mutualism, commensalism, parasitism, and others.
3. Define mutualism: In mutualism, both organisms involved benefit from the relationship. For example, in plant roots, mutualism can occur between plants and mycorrhizal fungi, where the fungi help the plant absorb nutrients, and the plant provides carbohydrates to the fungi.
4. Define commensalism: In commensalism, one organism benefits while the other is neither helped nor harmed. An example in plant roots could be certain bacteria that live on the roots and benefit from the environment without affecting the plant.
5. Recognize the correct answer: Based on the definitions, mutualism and commensalism are two types of symbiotic relationships commonly found in plant roots.
