Which of the following can lead to poorly coordinated muscle movements due to alcohol?

Over-consumption of alcohol can lead to poorly coordinated muscle movements due to its effects on the central nervous system. When a person consumes excessive amounts of alcohol, it depresses the brain's functionality, impairing motor skills, reaction times, and coordination. The neurological pathways responsible for muscle control become hindered, resulting in the inability to move smoothly and effectively. This is particularly evident in activities that require precise motor functions, such as walking, writing, or operating machinery.

In contrast, factors like body types, fatty food intake, or sleep levels do not have a direct, significant impact on muscle coordination when it comes to alcohol consumption. While they may influence individual tolerance or overall health, they do not inherently cause the same degree of impairment in coordination as over-consumption does.
