The correct answer is D. House cats, lions, and tigers belong to the same class and family.
Explanation:
Taxonomy classifies animals using different levels such as kingdom, family, order, species, etc. that show the features of the organism and its relationship or similarities with others. In the chart presented, the only level that is different for the three animals is the last one, which is the species level because in this the cat is classified as Domesticus, the lion as Leo, and the tiger as Tigris. This implies the other levels including the class (Mammalia or mammal) or family (Felidae) is the name of the three animals. This makes the last answer correct and shows these three animals are closely related.

In an experiment of DNA isolation, a squashed and refrigerated strawberry was added in a isopropanol solution after filtering it. It can be seen DNAs are starting to isolate from the strawberry extract in the form of fluffy bubbles.
