Curve B represents a Type III survivorship curve, which is characteristic of an animal that produces numerous offspring, but only a small fraction survive to adulthood. This is illustrated by the steep decline in the curve at the beginning, indicating high mortality rates among the young. On a logarithmic scale, this would appear as a straight line with a negative slope, as seen in Curve B. Curve A represents a Type I survivorship curve, which is characteristic of animals that have few offspring but typically provide parental care, ensuring high survival rates among the young. Curve C represents a Type II survivorship curve, which is intermediate between Type I and Type III, and is indicative of relatively constant mortality rates throughout the animal's life. None of these curves correspond to the scenario described in the question.
