Answer;

Explanation;
Symbiosis involves the interactions of two species living together; it may be mutualistic, parasitic or commensal.
Mutualism is a type of symbiotic relationship where both organisms involved benefit from the interaction.

Answer:
The correct answer would be C: bacterial plasmids.
In plants, genetic transformation is usually achieved with the help of bacterial plasmid, especially Ti plasmid.
Ti plasmid is a tumor-inducing plasmid generally present in <em>Agrobacterium tumifaciens. </em>This bacteria has a natural ability to infect plant cells and caused tumors or crown gall disease in them. It is also known as natural genetic engineering of plants.
The modified or non-virulent Ti plasmid is used to transfer the gene of interest in the plants.
