European starlings are agricultural pests. They damage crops and berries. European starlings also aggressively compete with native birds for the insects they eat. ... Large numbers of European starlings can cause dangerous and expensive damage to jet engines when they get sucked in.
The correlation coefficient (r) indicates a strong positive correlation with r = 0.9. The stronger the bond, the closer the relationship. Option B is true. As it is nearly 1 so it is the correct.
<h3>What is the Hamilton Rule?</h3>
Hamilton established the rule governing the costs and benefits of altruistic behavior in organisms. Here in rB>C, the r is relatedness between the beneficiary and the cost to the donor. The stronger their bond, the more likely it is that one will make a sacrifice for the other. In the parent-offspring case, the relatedness is 0.5 because half of the genetic content comes from each parent to the offspring. The greater the genetic distance between two people, the lower the r value and the lower the likelihood of altruism.
Hence, option B is correct as here r is 0.9, which is the highest among all four options.
