EASY QUESTION BRAINLIEST!!!Cladistics is a way of classifying organisms by examining the characteristics of their ancestors and descendants and depicting the relationships in a cladogram. Which of the following best describes a challenge in classifying organisms this way?A) There are millions of species on Earth, and a cladogram is not a practical means for classifying all of them.B) It is impossible to tell which organisms are most closely related to each other using a cladogram.C) Cladograms are detail-oriented and do not provide a useful understanding of evolutionary relationships. D)There is a limited number of ways to organize the information, so most cladograms end up looking very similar.DON'T TAKE AN ANSWER FROM ONLINE. I WILL CHECK
