The correct answer is: C. QRSP
The sentence is about the relationship between predators and prey. It states that life is hazardous, and that many animals are killed and eaten by other animals. Predators have continued to evolve adaptations that enable them to locate and kill prey, and prey have evolved adaptations that reduce the risk of being eaten. This creates a special kind of arms race with elaborate strategies and counter-strategies for attack and defence.
Option A, QPRS, is incorrect because it puts the sentence about the evolution of predators before the sentence about the evolution of prey. This is not the correct order, as the evolution of predators is a response to the evolution of prey.
Option B, QRPS, is incorrect because it puts the sentence about the evolution of predators after the sentence about the arms race. This is not the correct order, as the arms race is a result of the evolution of predators and prey.
Option D, SQRP, is incorrect because it puts the sentence about the arms race first. This is not the correct order, as the arms race is a result of the evolution of predators and prey.
Therefore, the correct sequence is C. QRSP.
