Answer 2

The Correct solution is Option b, Super Class Pisces.

• Lungfishes, lobbed finned fishes, and ray-finned fishes are all members of the class Osteichthyes, which is part of the superclass Pisces.
• The bony fish, or Osteichthyes, is a complex taxonomic category of fish with skeletons predominantly made of bone tissue.
• They differ from the Chondrichthyes, which have skeletons made primarily of cartilage.
• The vast majority of fish are members of the Osteichthyes order, which includes 45 orders, 435 families, and 28,000 species.
• It is the most diverse group of vertebrates on the planet today.
• The ray-finned fish (Actinopterygii) and lobe-finned fish (Sarcopterygii) are the major two types of Osteichthyes.
• Bony fish fossils date back to around 420 million years ago, and they're transitional fossils with a tooth pattern that's intermediate between a shark and bony fish tooth rows. 
• Bony fish have a generally stable cranial bone structure and a rooted, medial insertion of the mandibular muscle in the lower jaw.
• Large dermal bones encircle the head and pectoral girdles.
• A sclerotic ring of four tiny bones supports the eyeball, but this feature has been lost or modified in many modern species.
• Placoid scales are not produced by bony fish; instead, they are made up of three types of scales that do not pierce the epidermis.
• Cosmoid scales, ganoid scales, and teleost scales are the three types of scales seen in Osteichthyes.
