Answer:
The correct answer is option A. "Squirrels will emigrate and leave the population".
Step-by-step explanation:
Squirrels are small mammals that need constant sources of food to survive, because they spend much of their lives running from predators and searching for food. If squirrels face the lack of food in their regular habitat, such as the scenario proposed in the question, most likely the squirrels would respond by emigrate and leave the population. Squirrels migration is a common activity and is well recorded, particularly during fall season when more often they face lack of food and lack of nesting places.
