C) Aurelia
D) Obelia

Answer 1

Jellyfish and sea jellies are the informal common names given to the medusa-period of certain gelatinous members from the subphylum Medusozoa, a significant part of the phylum Cnidaria.

Complete answer:
Jellyfish are fundamentally free-swimming marine creatures with umbrella-shaped bells and following tentacles, although a couple are secured to the seabed by stalks rather than being mobile. The bell can throb to give drive to profoundly proficient motion. The tentacles are equipped with stinging cells and might be utilized to catch prey and protect against predators. Jellyfish have a complex life cycle; the medusa is regularly the sexual stage, which produces planula larvae that scatter generally and enter a stationary polyp stage prior to arriving at sexual maturity.

Jellyfish is also known as Aurelia. They are boneless creatures that drift freely in the seas. The body of the jellyfish is composed of a non-living jellylike substance called mesoglea. The jellyfish utilize their appendages to the catch and sting their prey. They are found in the Atlantic Ocean, the Arctic Ocean and the Pacific Ocean.

Hence the correct answer is option ‘C’.

Note: The primary component of a jellyfish is the umbrella-formed bell. This is a hollow structure consisting of a mass of transparent jelly-like matter called mesoglea, which shapes the hydrostatic skeleton of the creature. 95% or a greater amount of the mesogloea comprises water, yet it also contains collagen and different fibrous proteins, just as meandering amoebocytes which can engulf debris and bacteria.
