Answer to the Question

The bone that forms the lower jaw is the mandible.

Explanation

The mandible, also known as the lower jawbone, is the largest and strongest bone of the face. It plays a crucial role in holding the lower teeth and facilitating movements necessary for chewing and speaking. The other options:

1. The maxilla - This is the upper jawbone, which holds the upper teeth.
2. The ethmoid bone - A complex bone located between the nasal cavity and the orbits, it is not part of the jaw structure.
3. The zygomatic bone - Commonly known as the cheekbone, it does not serve as a jawbone.

Thus, selecting the mandible is correct for forming the lower jaw.
