Answer:
An older female squirrel that sounds an alarm call to warn her relatives of an approaching aerial predator
Step-by-step explanation:
Kin selection is the evolutionary adaptive strategy that increases the survival rate of the organism by increasing the reproductive success of the genes and other close relative genes.
The organism increases the chance of survival of the close relatives and their offspring at their own cost.
The kin selection behavior is observed in many species including humans, bees, wasps, squirrels, and many others.
In the given question, the squirrel especially an old squirrel gives an alarming call when a predator comes in their range which allows enough time to run away from the predators and increase the reproductive rate of the population.
Thus, the selected option is correct.
