c) Skull
d) Foot

Answer 1

The stirrup, known as the stapes, is a tiny bone in the middle ear that fits into the oval window of the inner ear, making the correct answer a) Ear.

Step-by-step explanation:

The stirrup, also known as the stapes, is one of the tiny bones referred to as ossicles within the middle ear. It plays an essential role in our ability to hear by transmitting vibrations to the inner ear. The three ossicles are collectively named the malleus (hammer), incus (anvil), and stapes (stirrup). In the context of the question, the correct answer is: a) Ear. The stirrup is the smallest and fits into the oval window of the bony labyrinth in the inner ear to facilitate the transduction of sound waves.
