Answer:Flippered and charismatic, pinnipeds (which includes seals, sea lions, and walruses) are true personalities of the sea. Like whales, manatees, and sea otters, they are marine mammals, meaning millions of years ago their ancestors evolved from a life on land to a life at sea. Today, they remain creatures of both land and sea. Though able to walk on land, they are truly at home in the water. Strong flippers and tails propel them and a streamlined body helps them cut through the water efficiently.
It’s easy to tell the enormous, tusked walrus from other pinnipeds, but seals and sea lions are easy to confuse. The easiest way is to look at their ears—sea lions have small ear flaps while seal ears are nothing but small holes.

A dichotomous key is defined as a biological tool for identifying unknown organisms to a particular taxonomic level. It is constructed with many levels and series of couplets.
So, by observing the given dichotomous key, it is concluded that the correct answer is Option A- Organism X and Z have at least one observable trait in common in this dichotomous key.
