Hint:The baleen plates are usually defined as webbed plates that are arranged horizontally used for filter feeding. Baleen plates usually act as a filter. The main function of the baleen is to catch the tiny organisms in the sea water.
Complete answer:
Baleen is mostly used for preparation of baskets, backscratchers, collar stiffeners, switches, and crinoline petticoats because it is tough but flexible. Baleen was commonly used as a creased paper because of its flexibility. Baleen is also referred to as whalebone. The use of the whalebone or baleen is now replaced with synthetic materials like plastic and fiberglass.
Now let us collect some information about the given option :
A) Blue whale : The blue whales are aquatic animals that live in water and baleen plates are a filter feeding system present inside the mouth of baleen whales. Thus, this option is exactly correct.
B) Shark : the shark are also aquatic animals but they have teeth provided in their jaws . Their teeth are triangular in shape and it is so hard that it can cut anything like a knife. It is used to eat and kill prey.
C) Dolphin : Dolphins have 80-100 teeth in their jaws. They do not only use teeth to cut but they use their teeth to grab, grip and secure prey and then eat it as whole. They have equal sized and conical teeth.
D) Archaeopteryx : it is the oldest living fossil. It is a connecting link between reptiles. Like birds it contains a full set of teeth and a toothed beak.
Hence the correct answer is option ‘A’ blue whale.
Note:Instead of teeth baleen whales have baleen. Baleen acts as a filter. Once the whale is underwatering it opens its mouth and pushes out the water and animals as small fishes remain inside as a source of food. The whales are aquatic animals and baleen plates are a filter-feeding system present inside the mouth of baleen whales.
