Correct option is B
The correct answer is (b) The ear.
· The 'hammer', 'anvil', and 'stirrup' are common names for the three tiny bones in the middle ear known as the ossicles.
· Their scientific names are malleus (hammer), incus (anvil), and stapes (stirrup).
· These bones are crucial for hearing as they transmit sound vibrations from the eardrum to the inner ear.
· The malleus connects to the eardrum, and the vibrations travel through the incus and then to the stapes, which passes them to the cochlea in the inner ear.
· The stapes is the smallest bone in the human body.

· The vertebral column: The vertebral column, or spine, consists of 33 vertebrae that protect the spinal cord and support the body's structure.
· The ear: The ear contains the ossicles, which are vital for hearing. It also includes other parts like the outer ear (pinna and ear canal), the inner ear (cochlea and vestibular system), and the middle ear (eardrum and ossicles).
· The elbow: The elbow joint connects the upper arm bone (humerus) to the forearm bones (radius and ulna). It does not contain the hammer, anvil, or stirrup bones.
· Ribcage: The ribcage is composed of 24 ribs, which protect the heart and lungs. It does not include the hammer, anvil, or stirrup bones.
