he correct option is Option 2) Lampreys and hagfishes.

Jawless fishes are a group of primitive fishes that lack jaws. They are known as Agnatha, and the two main groups within Agnatha are lampreys (order Petromyzontiformes) and hagfishes (order Myxiniformes).

Lampreys and hagfishes both belong to the category of jawless fishes. These animals have evolved unique adaptations to compensate for the absence of jaws. Lampreys are characterized by their sucker-like mouth, which they use to attach to other fish and feed on their blood and body fluids. Hagfishes, on the other hand, are known for their ability to produce copious amounts of slime as a defense mechanism.
