If the grasshopper population had a major increase, it would provide more food for predators that rely on grasshoppers as a food source. In a typical food web, an increase in the population of herbivores like grasshoppers would likely lead to an increase in the populations of their predators, such as snakes or frogs, depending on the specific dynamics of the ecosystem.
Therefore, the most likely outcome is that the snake population would increase in response to the greater availability of grasshoppers. The increase of grasshoppers could also potentially lead to more food for other predators, like frogs, which may also increase, or it could lead to competition among predators for resources.
In summary, the correct response would be: The snake population would increase.
