Which muscle acts as the floor of the mouth?

Geniohyoid
Mylohyoid
Digastric
Stylohyoid

The correct answer is: Mylohyoid

The mylohyoid is the muscle that acts as the floor of the mouth. This muscle works to move the tongue and jaw while also helping to support important structures in the mouth. Options A, C, and D are all located in the neck area and are involved in movements of the tongue and jaw but these muscles do not specifically act as the floor of the mouth. Therefore, they are incorrect options. Knowing the location and function of each muscle can help in selecting the correct answer.
