Insect herbivory is likely to affect the competitive relationship between the species in that a plant affected by these insects will have a hard time competing with those who are unbothered by the insects.

Although I could not locate the Graph or options for this question online, I can offer a general assessment to help you answer the question.

Insect herbivory is when insects consume plants or parts of a plant as their main food source. Interestingly, this term also applies to those insects who do not harm the plant, but consume the pollen, etc.

However, focusing on harmful insect herbivory, we can assume that in the presence of these insects a plant will have a hard time staying alive or mating effectively due to the damage caused. Therefore, we can assume that the plant on the left will not be able to stay competitive.
