A Correct answer
Explanation

The non-dominant parietal lobe integrates the contralateral side of the body with its environment enabling people to be aware of this environmental space, and is important for abilities such as drawing. Lesions of the right posterior parietal visuocortex (i.e. parietal-occipital cortex) most likely produces visual neglect.
