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.

<span>Light goes through the cornea first. This is the clear covering over the pupil and iris. The cornea bends the light and forms an image. The light then passes through the pupil, which is the dark circle in the center of the iris, the colored part of the eye. The pupil controls the amount of light that enters the inner eye. Then the light goes to the lens of the eye. The lens is clear and flexible and focuses an upside-down image onto the retina. When the retina senses the image, it sends impulses to the optic nerve, and the optic nerves transmits them to areas in the brain that flip the image upright.</span>
