Understanding the Answer
Let's break down why this is correct
Answer
The best way to tell the iris species apart is to look at petal length and petal width. These two measurements change the most between the three species, while sepal size stays similar across species. When you plot petal length versus petal width you get three distinct clusters that match the species labels. For example, a flower with 5. 1 cm petal length and 1.
Detailed Explanation
The two petal measurements separate the species very well. Other options are incorrect because People think sepal size is the key, but sepals are similar across species; Mixing one sepal and one petal measurement is not enough.
