e. D and F

Answer:

The correct answer is e. D and F

Explanation:

Organisms can be classified into seven major levels that are kingdom, phylum, class, order, family, genus, and family. The highest level of classification is the kingdom and the lowest level of classification is the species.

When we move from the higher level of organization i.e., from kingdom to the lower level of classification i.e., towards species then the similarities between the organisms increase and the number of organisms decrease and vice versa happens when we move from species to kingdom.

So, the class is a higher level of classification and order is at lower level than class, therefore, organisms in order will have the greatest degree of structural homology. Therefore the right answer is e. D and F.

The organisms with a greater degree of structural homology are D and F. Thus option E is correct.

The classification of organisms has been based on the seven major levels, accordingly:

  1. Kingdom
  2. Phylum
  3. Class
  4. Order
  5. Family
  6. Genus
  7. Species

The Kingdom has the been the highest level with broad category. The organism in this level shows lesser similarities with the other organisms.

The Species has been the lowest level of classification. The organisms are similar to each other in their characteristics.

The organisms A, B, and C have the same class, while D and F are same order. In the classification, the order has been at a lower level and has more similarities in organisms as compared to class. Thus the organisms with a greater degree of structural homology are D and F. Thus option E is correct.
