The correct answer is Choice A: Individuals with favorable traits are more likely to survive and reproduce.

Darwin's theory of natural selection is based on the idea that individuals within a population exhibit variations in their traits. Some of these variations may be more favorable for survival and reproduction in a particular environment than others. Individuals with these advantageous traits are more likely to survive and pass on their genes to the next generation through reproduction. Over time, this process leads to the accumulation of these favorable traits in the population, as they become more common due to natural selection.

The correct answer is Choice A: Individuals with favorable traits are more likely to survive and reproduce.

To arrive at this answer, you need to understand the basics of Darwin's theory of natural selection. First, it's important to note that natural selection is a process that occurs in populations over generations, influencing the traits of a species.

Darwin observed that there is variation among individuals within a population. Individuals differ in traits such as size, color, strength, or speed. Some of these traits may be more advantageous in a given environment compared to others. For example, in a population of birds, individuals with longer beaks may be better suited for reaching food sources, like insects hiding in tree bark.

According to Darwin, individuals with favorable traits are more likely to survive and reproduce. This is because these traits give them a better chance of obtaining essential resources, avoiding predators, or competing for mates. As a result, individuals with advantageous traits will pass on these traits to their offspring, increasing the frequency of these traits in the population over time.

Choice B, "There is no variation in organisms in a population," is incorrect because variation within a population is a fundamental aspect of Darwin's theory. Without variation, there would be no differences in traits to be selected for or against.

Choice C, "Only a small number of offspring in a population are born," is incorrect because the number of offspring can vary among species, and it is not a defining principle of natural selection. While it is true that not all individuals survive to reproductive age, the number of offspring produced by individuals can also be influenced by other factors, such as resource availability or reproductive strategies.

Choice D, "All individuals in a population have the same genetic traits," is incorrect because natural selection acts on genetic variation within a population. If all individuals had the same genetic traits, there would be no variation for selection to act upon.

In summary, Darwin's theory of natural selection states that individuals with favorable traits are more likely to survive and reproduce, leading to the increased prevalence of these traits in subsequent generations.
