These are all part of the head or skull. The cavities of the
skull surround and protect the brain and sensory organs. There are five kinds
of cavities of the skull which are:
nasal cavity (paranasal sinuses is included here) - The
nasal septum split the respiratory system into two lateral halves, the nasal
cavity is also part of the respiratory system.
<span>cranial cavity - The large cranial cavity is split
into a posterior cranial fossa and an anterior cranial
fossa, a middle cranial fossa. Its function is to support the
brain.</span>

oral cavity - The oral, or buccal, cavity (commonly called
the mouth) is a cavity of the head rather than a cavity of the skull because of
its fleshy and muscular floor.
orbital cavity - supports and defends an eyeball and its linked
muscle, vessels, and nerves.
<span>middle ear cavity - From outer to inner, three small bones-malleus,
incus, and stapes are situated within the middle-ear cavities in the
petrous part of the temporal bones.</span>
The correct answer is Protozoa.
A class of single-celled, non-prokaryotic organisms known as protozoa.These could either be parasitic or free-living in nature. These are heterotrophs that procreate via binary fission in an asexual manner. Numerous unrelated or tangentially related organisms make up the Protozoa. Sarcodina, Flagellates, Ciliates, and Sporozoans are the four main divisions. There are two stages in the life cycle of certain protozoa: the proliferative stage (trophozoites), and the resting stage (cysts). Trophozoites are the proliferative stage of the protozoa, which is when they divide and reproduce. The protozoa can tolerate adverse environmental circumstances like toxic chemicals, intense heat, and nutrition and water shortages because of their resting cyst shape.
