A species can be described as a group of living organisms that are able to live together and can produce fertile offsprings. For example, Texas bluebonnet plants are a species of plants which will interbreed and produce fertile offsprings.
Other options like option D are not correct because a community consists of different species which live and interact with one another at a particular time in a particular area. The different species cannot interbreed. For example, a community consisting of Texas bluebonnet plants, other trees, grasshoppers etc.
