Motor skills are associated with the frontal lobe of the brain. The frontal lobe is located at the front of the brain and is responsible for various cognitive functions, including motor skills and voluntary movements. It plays a vital role in the planning, initiation, and execution of movements. It also helps in coordinating different muscle groups to perform complex actions.

The parietal lobe, on the other hand, is responsible for processing sensory information like touch, pressure, and spatial awareness. The temporal lobe is involved in auditory processing and memory. The occipital lobe is responsible for processing visual information.

Therefore, option 1, the frontal lobe, is the correct answer for this question as it is specifically associated with motor skills.
